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 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 49

I came into the church at 21, but that is as far as it went. I was so confused about what love is. I couldn’t find it in the bible, because I am not a person that can read between the lines. I have no logic. I have read many, many books; trying to figure out the crux of the matter. They were helpful, but something was still missing. I have become very frustrated to the point of crying out to God, “Where can I go?”  I needed some basics.

I found two books, written by Timothy Jennings, MD, to be very helpful. God showed me that I had lived my whole life in fear. I didn’t even see it. Now, I do. God is so good.  I discovered the “The Remedy”  Dr. Jennings new book, “The God-Shaped Heart!” Oh, I was so excited, I purchased them right away.

I can get rid of most of my books, because “The Remedy” brings the Love of God out so clearly, even I can’t miss it. Now, I want to sit and read my Bible. Wow, what a revelation! It is just simply Awesome! I am so grateful to Jehovah Almighty for hearing my prayer for more understanding! I am so encouraged!

I have been sharing Come And Reason Ministries Bible study lessons with several folk. You have such a beautiful view of the plan of salvation. If we had this message preached when I was young, my generation would still all be in church.

Testimony 48

I just want to tell you how blessed I have been reading “The Remedy!” It has become a daily part of my devotional relationship with God. In it I have found a God of love and a God that loves me! The bible has come alive for me! It is the first time that I can say that I have felt hope fill my heart as I have read God’s word. This is good news I can share! Thank you, Dr Jennings! Thank you for your heart for others. I can’t put into words how this has set me free! It has strengthened my trust and love for God.

Testimony 61

I grew up in a prominent protestant church and had what I like to call religious anxiety. I’ve always had questions about God and Salvation that no one could seem to answer.  I didn’t know how to find resolution. During 2020, at the height of my anxiety, I fell to my knees and begged God to show me truth and light and to give me the hope that I’ve been longing for. Days later, I stumbled upon your online videos and it was like a veil was lifted and EVERYTHING made sense! For the first time in my almost 39 years of life, my religious/spiritual anxiety has lessened. I feel a sense of freedom and peace I’ve NEVER had before… and it’s all because my view of God has changed. Thank you!

Testimony 13

I borrowed “Healing The Mind” DVDs from a friend and showed them at my home for a small gathering of women friends. Neither of my friends are Adventist, but they both enjoyed and embraced the messages you taught. In fact, one of the ladies prayed out loud in our group and that was the first time she had ever had public prayer.

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 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!

I’m a youth leader in South Africa. We as a youth group are currently using a lot of the material on the Come and Reason site. Since we’ve started using the material, our youth group has grown.

Testimony 32

The message [of Come And Reason Ministries is] for all Christians (and those who may become Christians) and not just Adventists or any other group. It is difficult to imagine why any [anyone] with intellectual and spiritual honesty could find fault with the way you explained the healing substitution concepts and the truth about God’s character, though I know some will reject and criticize. On behalf of those in our group near Tacoma, WA, thank you and your staff for all of the hard work and for sharing the Gospel in this manner. God’s message of healing love will be carried to the whole world and then Jesus will come – He promised it.

Terry U., Tacoma, WA, USA

 

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.

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.
