Washington State University ADCAPS - Marijuana Effects
- Reduces levels of testosterone, which equates to reduced ability to gain lean muscle mass. Based on this, one can say "If you smoke weed don't bother going to the weight room."
Umm...interesting...
- Reduces libido and sperm count
- Produces sperm with abnormal chromosomes
- Disrupts menstrual cycles
- Produces less healthy eggs in women
- Development of the mammary glands (gynecomastia) in men
These can happen, under heavy use, in some cases. Well, I haven't found an actual source on the last one there, but I will give them it since the rest are real issues that can arise.
- Studies show that THC damages the hippocampus, a critical part of the brain in terms of learning and memory
Actually, it only has temporary effects on the brain, not permanent. Stop smoking, the effects go away. So "damage" is a bit of a strong word to use really. Smoke that may be present, like if using pot in joints, blunts, bowls, bongs, etc., on the other hand is a major issue for the brain, thanks to lowered O2 levels in blood going to the brain case. That isn't the fault of THC though, but it is a reason to advocate for vaporizing and edibles.
I love that one. Lazy people are lazy, studious people will be studious. Pot does not cause either. I know a LOT of pot heads (ironic, since I do not like doing it or smelling it, but that is neither here nor there), some of whom are college grads with degrees and good jobs and some of whom are nobodies. But again, it had nothing to do with pot either way.
"Amotivational Syndrome" is, frankly, hogwash. It is the stuff stupid propaganda like
Reefer Madness and such are made of - made up, unproven allegations with no backing but hearsay and conjecture.
I'd love to actually see that research. Not saying it is not true, but haven't seen it.
- Causes anxiety and panic reaction
It can also do just the opposite. All depends on the persons reactions, not on the drug itself.
- Increases heart rate and blood pressure
For a very short time, yes it can. Not any worse than jogging for a few minutes or going up a couple flights of stairs though - 10-20 bpm change in rate and a slight increase of pressure as well.
This could, potentially, be part of the mechanism that causes a panic reaction as mentioned above.
- Reduces the supply of oxygen in the blood (at a time it needs more oxygen due to increase HR and BP
HR and BP don't necessitate increase of oxygen in system. They generally are a reaction to expedite oxygen -hence increases during exercise and activity- but do not generate a need for increased blood oxygen levels in and of themselves.
I also note, despite being a release from the health center for Washington State, they left off the end mark for that parenthetical. Very bad image there, glad I don't go to WSU.
- Decreases effectiveness of the immune system
This, so far as I know, only applies to SMOKING cannabis and not to any other methods of use and is due the fact it is smoke. The cigar I just bought is likely to do the same if I smoke them very much, as did the cigarettes I smoked for several years.
