Marijuana 101 – Report from First Federally Funded Study of Marijuana’s Psychological Effects

Image

In 1970 Dr. Charles Tart published his results from the first federally funded study into the psychological effects of marijuana. This investigation and its findings are available for purchase under the title On Being Stoned. It is also available online here.

The study is rich with details regarding the characteristic and common traits of a marijuana high. It is something every person who has ever ingested marijuana should read and notice if they are nodding their head as they relate. Dr. Tart categorized aspects of human consciousness and developed a questionnaire for people of various levels of marijuana experience. The result is a guidebook of the many psychological changes that can occur when THC and other cannabinoids are in our system. (THC is the psychoactive chemical in marijuana that creates the characteristic high. The human endocannabinoid system was not understood at the time of this study.)

This federally funded study concludes that the benefits of marijuana far outweigh the downside risks physically and psychologically. Specifically Dr. Tart says “the known dangers of marijuana use are very small, while the known social cost of the present legal structure… is tremendously high.” (Introduction)

Dr. Tart also makes a comment about the possibility that marijuana users can become psychologically dependent on the plant. Tart says [psychological dependence] “is a nonsensical use of the English language, for psychological dependence simply means that people tend to repeat enjoyable experiences.” (Chapter 1)

The following is a summary of the “characteristic” and “common” traits that people experience after smoking various amounts of cannabis flowers. Descriptions of a marijuana high’s intensity range from Fairly, Strongly, Very Strongly, and Maximum.

As you read through this list, notice which of the qualities you consider to be worth repeating and which ones are a problem.  Often it’s difficult for us to share how our perception changes with marijuana. Something changes, but what? We’d love to hear your comments and personal experiences.

On a personal note, the main reason that i (the author of this article) entered into marijuana activism is due to the fact that the people i know in the marijuana community are some of the most generous, empathetic and authentic people i have ever met. As i experimented with my own consciousness by deliberately ingesting various amounts of marijuana and paying attention to what changed, my quality of life improved in every dimension i could conceive of evaluating the experience.

Don’t take my word for it. Try it for yourself. Start small if you’ve never ingested marijuana before. It’s not for everyone, but considering the plant is non-toxic (no one has ever died from overdose or chronic use) and less addictive than alcohol and caffeine, the biological and mental risks are low. Legal access to the plant is now widely available, so the chances the cops will knock down your door for inconspicuous personal experimentation is low. Don’t be paranoid. Clear your calendar, have a nice dinner, turn on some relaxing music, and let NC NORML know if you agree with any of these findings from the first federally funded study of the psychological effects of a marijuana high.

    1. The line between use and abuse is only as fine as the level of responsibility the user takes for his/her behavior. I know people who ingest marijuana several times every day and manage to passionately pursue their dreams. I also know people who smoke the occasional joint and do absolutely nothing with their lives. Abuse of marijuana happens when someone sacrifices long term gains for short term euphoria frequently enough their quality of life deteriorates within a state of denial.

    2. I take it to heal Cancer. It took time to get used to it. Now I find: when I am driving I am much more alert , observe more clearly = just missed an illegal left turner by an inch. Yes I feel lightly heady. I do sleep better. I wish everyone luck, success
      and common sense that is fighting cancer or any other ailments. It is worth it! CHEMO kILLS. I had enough after 2 years, My body almost got killed. Now I Have to heal my body. That is a slow and dreadful journey. I had lost a lot of weight and only weigh 46 KG now, whereas my normal weight would be 55 KG.
      There are many side effects of Chemo, too many to list and the Pharmaceutical deny it. I am living proof!

  1. Thanks for finally talking about >Marijuana 101
