Not according to recent studies (at least, not in the longer term). Interesting paper that adds some cogent fuel to frequently recurring debates.
Interesting study. Over time I am sure that the research will reveal that a little of this and a little of that, in moderation, doesn't really do you any harm. Which is what most of us know instinctively anyway ... no matter how aggravating people who're 'toked up' are :lol:.
I never felt any different one way or the other. Of Course I never inhaled. Those I know that did, were, a bit stupid acting for a time, but seemed to get better. All kidding aside, as Sukerkin said, very interesting study.
It has individual effects on individual people. The location and density of the cannaboid receptors dictates what gets affected and how. Physically, the THC causes the synapses in those receptors to enlarge, making them take longer to fire. If you have a low percentage of receptors it will have little effect on you and vice versa. This is the general physical explanation for the high. While it's indirect, it still affects the body's endocrine system, much like other drugs or alcohol and has a personality changing effect. Heavy users tend to develop high tolerances while light smokers tend to get hit by a ton of bricks each time, hence the similar findings. I certainly wouldn't consider the damage comparable to alcohol let alone crystal meth but it tends to interfere with learning. There are aspects that might actually help with retention but I can't speak of that from personal experience. I found it was like putting blinders on: good for linear thinking but not good for much else. Hot smoke on the lungs kills tissue and leaves sediment. I suspect that all smoke is somewhat carcinogenic and increases your risk of getting cancer.
I know one person who used to use Cannabis - I never have and never will touch it myself, but whenever he used some, hed be a bit delirious for a couple of hours, but it wasnt really behaviour altering at all. It just spaced him out, then hed be no different when he got over it. So i figure its like Alchohol. Some people get sick, and cant hold it down. Others become quite hostile. Others just have hazy thought processes. In other words, different people react differently. Just an idea. And as such, some people may well let themselves be stupified by it.
Yeah well... uhh.... ..... ..... wh... ..what I got......... what I got to say is..... ..... (dammit).... wait .... umm.... what's the topic again?
I can spot a "pot head" a mile away. I have never been able to decide if its a cultural thing (they act like pot heads) or if its a physical thing (pot has made them idiots).
