How marijuana influences the brain

When you smoke marijuana (or ingest it through another route such as eating or tea brews), it influences the work of the body for a short time, or for as long as the effects of marijuana don’t wear out. But, smoking a lot every day and for a long period of time can cause some functional changes in the brain.

What THC does to the brain?

THC is a key ingredient that marijuana contains, but there are many other ingredients in marijuana. THC can quickly pass the blood-brain barrier when smoked, while it needs about 30 minutes to an hour for its effects to be felt when users eat it. THC attaches to the cannabinoid receptors in the body and the brain. In the brain, there are several sites where with a higher density of cannabinoid receptors, which normally react to natural THC-like chemicals in the brain. However, the THC from marijuana overactivates these regions of the brain resulting in some short-term effects, such as:

  • alteration of the senses
  • loss in time and space
  • lowered reasoning ability
  • memory lapses or memory loss
  • mood changes
  • panic
  • poor body coordination

Over time, repetitive exposure to high and frequent doses of THC can lead to some long-term and adverse effects on the brain in individuals, especially in individuals with underlying psychological disorders. These side effects of marijuana include:

  • addiction
  • depression
  • functional changes in the stress and reward regions
  • impaired ability to learn and retain information
  • lower concentration capacity
  • mood swings
  • personality changes
  • psychological dependence
  • short attention span
  • suicidal thoughts

Hello there I’m in my 40’s and have smoked marijuana only a few times in my life. The other night I decided to eat some marijuana brownies after a couple of drinks. Needless to say I had one of the worst nights of my life – paranoia, depression you name it. I guess I greened out for about 3 hours.. Over the past 6 days I’ve still had hot and cold flashes, depression and moments where I’m not in my own body (weird I know but true). Just when I think I’m getting better my whole body goes flush and start to have anxiety. I had to go to the doctor on day 3 as it was so bad – my doc gave me some meds to help settle things down. I’ve read some other blogs and its seems this happens more often than people think. My question is have you heard of this going on for a long time or do the symptoms go away….

If you are a cannabis user and you stop taking cannabis for a year, will you get a stronger high the next time you do it?

Hi Rafi. There is only so much you can do as an individual when a loved one has a problem with dependence or addiction to a substance. You can seek professional help from a therapist or a counselor for yourself first, and then for your girlfriend. Talk therapy can help you learn how you can act and what you can say around her to maybe motivate her to quit. But most important of all, you will continue to take care of yourself throughout the process.
