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 40

I was brought up in a different faith and have been petrified my whole life of God. I believed that I would burn in hell for eternity. When I was 12 I started pursuing the things of this world, but for the next 45 years the Spirit was always calling me, as I knew there was a God through nature. I could see the vast sea of stars in the universe and knew there was something bigger out there. Five years ago, through a Revelation seminar, I was blessed to learn about God’s character and government.

Then I found Come and Reason Ministries and have come under some extreme pressure when I speak about the ministry. One time a member sent me an internet article titled “Whats wrong with Tim Jennings?” I asked her what she thought of it and she said “I don’t know, I didn’t read it.”

I have always wanted to find out for myself the truth about God, so I stayed with the Design Law construct and have been liberated to understand the big picture. Once we consider Design Law, all other Bible stories and prophecies seem to fit perfectly. It is truly beautiful to see people grasping how God operates this Universe of Love and the liberation it has provided in their lives. It blows my mind to see how consistent Design law is with what our founders believed. I hear statements like “This makes so much sense.”

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 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!

Dean P., Arlington, TX, USA

 

Testimony 47

I can’t even begin to thank you and your ministry enough for introducing me to the Truth about a loving and merciful God! I have my daughter and her in-laws to thank for sharing with me “The God-Shaped Brain” as well as your website. I listen to the Bible study class lessons on my daily walk. May God continue to bless your thirst-quenching ministry!

Testimony 45

I have been confused for years about what [christianity] calls [its] most disgusting teaching. It has never made much sense to me and for that reason has been evermore empty. I have listened to your class off and on and have struggled determining what is truth, because of the resistance design law encounters in the church. So, I thank God for your ministry. What you teach makes sense. It’s logical and backed up by the power of love. I have never seen that in Christ until now. I am astounded by the insight that is found when we look at God’s ministry through design law. All strength to this message, as I believe it to be the power of God.

Testimony 25

I just want to say thank you so much for your conversations via YouTube. I regularly tune in to your lectures, “Let’s Talk” sessions, and many others. Through these I’ve found greater depth and meaning to God’s word. Thanks for all that you do and please continue. I’m currently working in the middle of Silicon Valley at Stanford University. I feel like God really has me in the right place right now and I’m sensing that your teachings might be part of it.

Testimony 53

I was so blessed by a friend who gave me your book, “The God Shaped Brain,” while I was sitting in church asking God to please help me learn more about Him and help me not to be so confused and scared. That was about 2 years ago. Your books have helped me to love God even more. I’m not confused or scared anymore! I have listened to all of your bible study classes and feel like I know the wonderful people that attend every week. Thank you for all that you’re doing in spreading the true message about God and His law of love. God bless you and your whole class.

Testimony 73

I have been truly blessed by your blogs and other resources. They have helped me to see things in a much brighter light and to reason things out better. Thank you so much for your ministry. Whenever I have the opportunity I pass along your material to my friends.

R. Noseworthy, Newfoundland, Canada

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.

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 62

I would like to express my thanks to the C&R team for creating a platform from which people can learn to trust in God and grow. My life is a witness to the effectiveness of this ministry. Without believing the truth about God as you have shown, I don’t know what my life would be like. I had given up on God helping me with certain sins – it was all useless. Given that the scripture is clear and God is so good, how could I have betrayed him so many times? I was a yo-yo christian; spinning up and down. My faith and enthusiasm was driven by discoveries/threats that prophecy is about to be fulfilled. But when I watched your “Healing the Mind” seminar, it was like a light finally went on. I could see God had no plan to hurt me, the danger came from sin, and that He is working to protect me and strengthen me. Thank you for allowing God to use you. The message God gave C&R saved my life!

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.

Testimony 43

Two years ago I stumbled upon your book, “Could It Be This Simple,” and then found “The God-Shaped Brain” videos on YouTube, your bible study class, and the ‘Come And Reason’ mobile app. I shared your book with a friend and after nine months of showing love, patience, and kindness this person has been changed by the love of God, too. The same love that healed me, I now express to other women in tangible ways, such as to a Baptist woman with high anxiety and childhood trauma. She was extremely happy and relieved when I shared about the so-called “judgment of God” and burning in hell. She had no desire to serve a God that was so harsh. I have repeated the phrase dozens of times to her. “What we believe has power over us, but we have power over what we believe…”

This message that you are sharing has changed my life. I will continue to serve other women and bring this message of God’s healing love to their lives by sharing your books, YouTube videos, and The Remedy Bible app. Keep up the good work. Don’t be discouraged. God is doing a mighty work in and through this ministry!

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 57

You have helped make sense of thirty two years of confusion. The material you freely provide reorganized so much of my life into such a beautiful pattern that has always been hinted at from within, but misguided with my training and what I was experiencing externally. My filipno parents, who were converted from Catholicism to SDA, were sincere and did their best to raise me the right way and I have deep respect for them. However, being immigrants and not understanding the language made for a difficult transition as I was growing up, which also applied to my spiritual growth as I learned the patterns of religion. I have been listening to as many bible study classes and reading blog posts as my time in a work truck will allow, searching for the practical applications of where spirituality and reality meet, and I thank you for helping me find that. You have helped me reach a point in which I can truly say that I love God, that I believe He loves me, and, like David, I delight in His law. God bless.

Emmanuel V., Calgary, AB Canada
