Marijuana – The Science Behind the Smoke

Marijuana – The Science Behind the Smoke

Twenty-eight states and the District of Columbia have legalized “medical marijuana” and 8 states have legalized recreational cannabis use. Does this mean that marijuana is harmless? That it is safe? That it is not addictive? What does the science actually reveal?

  • Cannabis is the most commonly used illicit substance in the United States and worldwide.
  • Cannabis is addictive and the younger one starts using it, the greater the likelihood of addiction.
    • One out of eleven adults (9%) who try cannabis become addicted.
    • One out of six adolescents (17%) who try cannabis become addicted (Hall, 2009; Volkowet al., 2014).

Cannabis has changed over the years and is much more potent today than just a few decades ago, thus increasing the risk of addiction, as well as mental health problems. In 1992, the average potency of delta-9-tetrahydrocannabinol (THC) in cannabis seized by the U.S. Federal government was 3%, but by 2016 the potency had increased to 11%, an almost fourfold increase! This increase in potency correlates with increased number of hospital admissions for cannabis-use disorders.

Cannabis contains more than 460 active chemicals and more than 100 unique cannabinoids. These are the compounds that interact with the brain’s cannabinoid receptors.

Cannabis (including “medical marijuana” in dispensaries) is not standardized in dose, potency, or chemical constituency, which means you don’t know what you’re getting from one marijuana sample to the next.

So, what does the published research demonstrate?

  • Most studies (70%) done on cannabis are deemed to have “high-risk of bias” due to methodological flaws and author biases.
  • Only 57% had appropriate participant blinding and only 24% had appropriate blinding of outcome assessors (this means preventing the participants and assessors from knowing who was getting real cannabis and who was getting placebo.)
  • Most research was done on oral cannabinoids, which contained only one or two of the more than 100 active compounds; only two studies involved actual cannabis (smoked in one study, vaporized in another.)
  • Thus, all the hype suggesting safety of cannabis is just that, hype and not science.

Of the studies that were well done, the researchers concluded that there was moderate evidence of medical benefit from cannabis for chronic pain and muscle spasticity. There was poor-quality evidence for the treatment of nausea/vomiting due to chemotherapy, weight gain in HIV, sleep disorders, and Tourette syndrome.

This means that the medical benefits are narrow and much more evidence is needed. However, since many states have legalized medical marijuana, it has led to the perception amongst young people that marijuana is not harmful.

The graph below shows how attitudes among high school students have changed from 1975 to 2013:

Another issue that perpetuates the false idea that marijuana is harmless is that it is “natural,” but natural doesn’t always mean harmless!  Consider tobacco, poison ivy, poison mushrooms, or foxglove (a plant from which the cardiac medicine digoxin is derived, in which a small overdose of it will stop the heart). All of these are natural products, but are poisonous or toxic. No, natural doesn’t always mean harmless.

Perception about marijuana is critically important and we must educate young people about the health damaging effects of it, just as we have done regarding tobacco.

Surveys show that 45% of U.S. high school seniors have used marijuana, 23% use currently, and 6% use daily (Johnston et al., 2016). The more marijuana is used the more damage it does to the brain. In a dose-dependent manner, adolescent cannabis use is associated with worse performance in school, work, thinking, increased psychiatric disorders, and worsened substance use outcomes (Pope et al., 2003; Fergusson et al., 2015, Jager& Ramsey, 2008; Meier et al., 2012; Randolph et al., 2013; Camchonget al., 2016, Fergusson et al., 2002; Patton et al., 2002; Moore et al., 2007, Patton et al., 2007.Volkowet al., 2014, 2016; Levine et al., 2017).

Cannabis use in adolescence is associated with increased incidence and worsened course of psychotic, mood, and anxiety disorders (Hayatbakhshet al., 2007; Moore et al., 2007; Gage 2016).

Several studies have documented that adolescents who smoke marijuana have a loss of IQ points, more than a standard deviation, that is never fully recovered after stopping marijuana use (Pope 2003, Gruber 2011, Meier 2012).

The bottom line is that marijuana is a neuro-active substance that has multiple damaging effects on the brain. It reduces IQ, increases mental illness, and increases the risk of multiple health problems. Furthermore, there is essentially no research on the more than 400 chemical compounds contained within cannabis.

We must move away from myth to truth and educate our young people on the dangers of this substance.

Remember, humans can pass laws to make marijuana legal, but we can never pass laws to make it healthy! Mature people are those who choose to operate in harmony with design law—the laws upon which life and health are built—so even when society makes something legal, if it is unhealthy, the mature won’t damage their bodies with it.

Testimony 46

Over the past couple of years God has been expanding my view of Himself and His character. Along my approximately 40-year journey, I have often had questions, but was hesitant to voice these and step outside the traditionally accepted thinking, for fear of admitting that I may in fact be eternally lost. In the recesses of my thinking has been the thought – if one blindly accepts (which is widely regarded as “real faith”) and does not question, is this really ‘truth?’ I often find it challenging to grapple with very theological ‘speak,’ but Dr. Jennings has a real gift of explaining spiritual concepts with clear practical examples. The weekly discussions are growing my Christian experience and slowly changing my view of how to live as a child of God in today’s complex world. Finally the whole Old Testament sanctuary teaching moved in my mind from fantasy to reality!

Testimony 52

Your unique way in spreading the truth is what we all need today. Most of us don’t recognize the contamination coming from all the lies and selfishness in the world. Because of our fear of death, we forgot how to live. Lies left and right. I was losing hope and faith, because of so many ideas that are always contradicting each other – so many questions answered by other, more complicated, questions – until I found your channel on YouTube.

You did not just give me answers, you also taught me how to answer new questions that arise in my mind. Now I see things differently. I see God’s mercy, grace, and Love everywhere, in spite of all the chaos that we all have done as humans. I don’t fear death anymore. Accepting the Truth and Love about God is truly a genuine Freedom from all the confusions, sufferings, selfishness, pain, and death.

I just wanted to say, thank you, sooooo much for revealing the real Remedy for our infected life. I have a new hope and now see the world in a different perspective!

Testimony 55

I was born [into the church], then I left it for many years. 10 years ago, I came back, but I could not take the hypocrisy and the lack of answers to the missing pieces. I struggled, but I did not abandon my commitment to know the truth. God is leading me to the simple understanding of his relevance and I am relearning what the church taught me as a youth… that he loves me, that he has led me to a knowledge of him such as I have never known. He is using Dr. Jennings to connect the dots that are now so apparent and hiding in plain sight!

Testimony 30

God lead me to your book “The God-Shaped Brain” while I was searching for another book about the brain and then to your interview about your book on HeartWise Ministries [where] I found out about [Come And Reason Ministries]. I’m now devouring the webcasts of your Bible studies. I have been so greatly blessed and I thank God so much for your courage to speak the Truth in love no matter what. Listening to you contrast the two opposing systems (laws) and digging deep to unearth the hidden treasures in the Bible makes me so incredibly happy and I feel very blessed to be part of your Bible Study Group although I live far away. I am just so excited that there is a group of people that is spreading the Truth about the character of God and it saddens me how few realize what our Father in Heaven is really like.

Testimony 67

I was introduced to Come And Reason by a friend of my mother-in-law, who gave me several CD’s of Dr. Jennings. The clarity of the message and recognition that God’s is a God of love was so clear, advancing beyond Dr. Maxwell’s message. However, grappled with Maxwell saying God used emergency measures for the fallen world. Now after several years of being a regular listener of the Come And Reasoning bible study class and attending Jennings’ meetings in Dallas/Fort Worth, TX, things are becoming clearer for me. Design law versus imposed law has added so much to my personal understanding of theology. This message has really impacted my work in counseling so many people miserable because they are searching for and trusting human governments to create order and peace or believing in a God who says love Me or I will kill you. I am grateful that I have an alternative view to offer my clients that makes sense. I teach a bible study class on a semi-regular basis and I value the materials that Come And Reason so freely offers to aid me in presenting this vital message. Thank you for continuing to provide advancement in our very limited understanding of a Infinite God that is rational and believable.

Testimony 41

I have been blessed by your ministry. I have experienced personally, and deeply resonate with, the God of love and the beautiful picture of God’s character that you present. I have seen your seminar series on YouTube, read ‘The Journal of the Watcher’ book, used your mobile app, and also listen/study the bible study lesson with you each week. I concur with many of the thoughts and perspectives that you share. I understand your conclusions on natural laws vs imposed law and the legal/penal substitution (incorrect diagnosis). This makes perfect sense to me.

Bless you for all you do.

Testimony 21

I am absolutly on fire with the message at Come and Reason! I can’t get enough! I’ve read your book, blog, and articles. I’ve listened to your Bible study podcasts, your radio show, and your series – all excellent! It wasn’t until the past couple of years that I have I like I’m becoming “healthy,” with more to share with others than just beasts and commandments! I used to be a Bible worker and preached when the pastors were gone until I had had enough. I didnt realize at the time what the problem was, but i know now… the message wasn’t properly focused. Now my flame is rekindled. All of your little examples are so perfect in explaining something “complicated” and making it easily understood! Now I’m trying to shape it into a life changing evangelistic series! Thank you!

Testimony 34

I was introduced to Come and Reason Ministries by accident, via a passing comment made in a bible study class we were visiting. I checked this website out and my life was changed. The understanding of the truth of God’s character, and how we apply it, is so right. The tricky part is consistently applying which “lens” to look through. As I began to understand, I started sharing the basics of this understanding with a discussion group I was leading and, suddenly, a lot of things started to make sense that never used to. At the same time, I enjoyed an amazing opportunity. I was able to conduct a full bible study at WORK! What an amazing experience! It is such a joy to share the truth about God and to share how it all fits in the war between God and Satan. So many people benefit when we have a correct understanding about how God works and who He really is! Thank you for this transformational understanding. Keep up the good work! God Bless you!

Testimony 37

Hearing Dr. Jennings’ presentations in person came at a pivotal moment in my spiritual journey that began about nine months ago, when the fault lines inherent in my belief system began to crack under questions that most reasonable people end up asking about God and His nature. These were questions I couldn’t find answers to, and they shook my faith. I was unable let it go any longer and be satisfied. My Christian experience became distant. I was afraid; the fear in me rose like thorns, pushing me away from Jesus. And then someone heard my questions and introduced me to this ministry, and my life has totally changed.

I can tell you that this new, “present truth” message is far grander and life-changing than when I shifted from being an agnostic and then a nominal Christian. It has radically altered my worldview, because it reveals a God that makes sense. It is a revolution. I believe that Dr. Jennings’ message is the final message that must go to the world. If any message could be called “righteousness by faith,” as abused as that term is by the right and the left, this is that message, because Jennings’ biblical message identifies a God who is different, whose character isn’t an impossible contradiction.

I walk this path now without fear. I see people differently, and the Holy Spirit burns in my heart. Many call Dr. Jennings’ message false and compromising, but it isn’t false, because I’ve seen the fruits within my mind and body. It is not compromising, because in this message is the only road to holiness that makes any sense. No longer do I behold a pagan god who is always angry and suspicious. Instead, I behold a God who is freeing and loving, always working for our good, and giving me every reason to love my enemy even to my own death, just as Jesus pleads with us. God is good.

I really enjoy with you the view of a gracious God. Thank you for sharing the work you are allowing the Lord to do in you.

Testimony 64

I’ve been reading the bible and walking with Jesus since I was around 16. I’m 42 now. I’ve mostly been alone in my walk although I went to several churches in different denominations. For the past 3 years God has been showing me His character of agape. It’s been a blessing and changed how I view God and my walk with Jesus. About a year ago I came across the power of love and the principles of design law. These teachings changed how I read scripture and have been such a beautiful blessing. I’m very excited and grateful for these truths. We share these truths of agape, design law and the reality of the principles of the two trees in the garden of Eden with people on Facebook and YouTube. People all over are learning to trust God and His agape design law which makes life possible. Thank you for everything you shared with me. May God continue to bless your ministry and lives.

Testimony 71

When I was 9 years old, I remember setting at our devotional table with a hunger and thirst for God that wanted more, deeper, BETTER. I can remember literally crying and pounding on the table, “I know these teachers didn’t mean to give us error. They taught what THEY had been TAUGHT, but didn’t ANYBODY READ THE BOOK?!?!?” It mattered to me then. It mattered to me as a teenager. It matters now as I teach bible classes. It didn’t have to be so hard as I watched so many give up and lay God’s great plan and gift of salvation aside as being “impossible.” Then, a friend sent me a link to Come And Reason’s website. I grew excited. YES! FINALLY! Then another friend told me to stay away, saying her son had just broken up with a girl because she was involved with Come And Reason and that “Tim Jennings preaches a false gospel.” But, AFTER many years of developing an authentic and, dare I say FUN relationship with Jesus, through the Holy Spirit I see this message has been around a LONG time, since the apostle Paul, Ellen White, Graham Maxwell, Ray Foucher, and yourself (though I admit, you’ve made me back up, rewind and replay the clips, and get out my well-worn Bible on a few things.) I’m so thankful I have found LIGHT during these DARK days. I am not alone.

Testimony 10

I personally download and listen to each of Come And Reason Ministries Bible study class lessons and PDF study notes to use when teaching my class. Really appreciate the class especially when Dr. Jennings is teaching. Thank God there are persons like him doing His work and traveling to share His beliefs.

Testimony 70

I have been watching you for many years and have learned to love God with all my heart. I was raised by a loving Christian mother that had been lied to about who God really was, so our religious upbringing was hell fire and damnation. As soon as I was old enough and moved out, I not only left the church, I ran as fast as I could to get away from it. Sad to say, it wasn’t until the past couple of years that I learned and understand who my Father really is and how much He loves me. I understand God’s Design Laws (which make sense) and when I’m teaching my church Bible study class, I’m able to really put to use the things I’ve been learning and Holy Spirit is leading. Thank you for introducing me to my Father of true, pure love. Everyday with Him is new and exciting. One thing that breaks my heart is that I didn’t know Him sooner. God Bless you and your ministry!

Judy Phelps, Reno, NV, USA

Testimony 1

Thank you! I love listening to the Come And Reason Ministries Bible study classes and am using some of your notes to get the lessons together that I will be teaching. You always have such good quotes and Bible texts and pull things together to make good sense.
