When I was young, all I knew was weed users. I tried it and it was never for me. I have family members who have used it for over 50 plus years.
Couple of observations:
If long time users don't get access to weed they get irritable/aggressive. Aggression levels depend on the person.
Schizophrenia development does happen in heavy users. Apparently its if your prone to it already. But an awful lot of my older mates ended up with it. Some people have full on mental meltdowns on it where they no longer can function.
The claim "weed doesn’t have a single death" is only partly true. Medically you won't OD. But the amount of guys that died due to the onset of depression/schizophrenia due to, or in combination with weed use is staggering. The amount of guys I cut down, or found stuffed in vehicles gassed is ridiculous.
They were from a wide cross section of society with heavy marijuana use the common factor.
Some guys can use it with no effects for years. As far as the toll on your body physically is concerned, then I think its one of the safer of the illicit drugs. You do get some random stuff. One guy I knew became allergic to everything, but it would be hard to pin pot on that. Bong cough is about the worst most get.
Its addictive. Some of my sons friends are out of control on this stuff. Most users can't stop using.
I have friends that are big time advocates. They have been on the "730 report" and other media extolling weeds values. I've watched their lives for upwards of 20 years plus. And if anything, pot held them back.
I remember when "skunk" came out in the 90s. A super strong strain of weed, mainly hydro. Don't quote me, but I think it was in the 5-12% thc range. Now we have stuff nudging, or over 30% thc. People put to much faith in, or over exaggerating the benefits of weed. Old studies on bush weed should be made redundant. They were in the 5% range.
It may have a lot of legitimate uses but I don't think its safe mentally, physically, or ambition wise.
