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 42

I am just writing to say that I have been so blessed by the teachings of Come And Reason Minitries recently. I watched last week’s bible study lesson on Youtube and am thankful that the error in the printed lesson guide you use was pointed out and this week’s study was of equal benefit, if not more so. My understanding of God’s nature has been very confused of late and I am so grateful for clarity in this matter. I have never really fully understood previously how a good God can cause bad things to happen and now I realise that He doesn’t, it’s a natural consequence of sin. May the almighty Father and His Son, our Saviour Jesus Christ, continue to bless your ministry.

Laura P., United Kingdom

 

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 2

I continue to enjoy your lessons every week. The more that I research your conclusions, the more I am convinced that the Holy Spirit has lead you to distill out the essence of human redemption. Thank you for your courageous stand for the truth.

S. G., TX, USA

 

Testimony 3

My husband is a pastor and I listen to your lesson almost every week. Thank you for helping me in my study life and to help me love the “real” God more.

C. F., NC, USA

 

Testimony 19

I truly believe that to know who God really is the first step to understand ourselves in a balanced and kind way, so the healing can take place. Your approach really makes sense – Thank you for your ministry!

A.M., Pittsburg, PA, USA

Testimony 24

I wanted to thank you very much for presenting your understanding of God. I’ve always been troubled by this question: Why did Jesus have to die? Since my conversion I understood that The Father & Jesus are one, I did not have issues with that. But was there not any other way to save us than for Jesus to die? I guess I actually had a question about God – if He is so wise, how come He did not find another way? I did not see the real ‘beauty’  in the cross. Only when you explained the picture in the medical context, Jesus providing medicine for my selfishness, have I started to finally ‘see the light’. Thank you so much. Your seminar, “Healing the Mind,” are absolutely marvelous & have shared them with my family and many other people, including colleagues at work. Thanks, thanks, thanks. May God bless you abundantly in your ministry.

M. W., Australia

 

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.

Anthony L., CA, USA

 

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 69

After reading your book, ‘Could It Be This Simple,’ someone was explaining Christianity in a way that made sense to me for the first time in my life. One morning, I simply prayed “I’m sorry and I love you.” As soon as I silently said that, I could literally feel God’s presence and light flood down on me from above and fill me up with love and joy. I sat there crying my eyes out, because I was so overpowered with this feeling of love and joy. It was just so incredible. I hope that more people can read this book and get a blessing from it. It’s really amazing.

Rachael H.

Testimony 26

Testimony 4

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.

R. V. N., South Africa

 

Testimony 31

It was very touching to hear the testimony of your class share how viewing God’s true character has changed their lives. My feelings are the same – there is so much freedom in knowing that God LOVES me – regardless of my… just, REGARDLESS! I’m still blown away by the true gospel, the fact that God is not ready to strike us when we fail. He is not arbitrary. He simply loves us and warns of the natural consequences because He can’t stand to see us suffer. I AM IN LOVE WITH THIS GOD!!!

Ceil V.,  UT, USA

 

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 6

I got the book “Could It Be This Simple?” a few months ago and the reading was wonderful and I was fascinated. I lent the book to a friend at work. She is having a difficult time and the book is helping her to find Jesus and I found this very exciting. She has asked me questions and I can see her life changing.

H. S., Australia

 

Testimony 74

Thank you so much for opening my eyes. I’ve been through a lot of ministries that just didn’t show the love of God that I felt he was. You have helped me to begin the process of true healing. I thought I was “too far gone,” now I know there’s hope in Jesus, because he loves us beyond what we can comprehend. Thank you again for all you do. I truly appreciate it and pray more people find you (physical at your studio and through this website).
