I have a feeling some people on this thread are posting while stoned.
I do find it amusing to read drug users trying to justify their habits by quoting rather dubious research and "facts".
I have friends who regularly smoke dope, they cant function without a joint for breakfast, and spend their day on a level of "high". To them it is their normal life, they do not feel under the influence because to them it is normality.
What they dont realise is how bloody boring they are most of the time, talking bollocks, and convincing themselves that they are somehow highly intellectual people who waffle on about conspiracy theories and how they know more than anyone else.
I smoked cannabis on and off for years, of all types. I havent touched any drugs now for almost ten years, but I was certainly no angel from my teens to my mid 30's. I know how it affected me while using, I know how it affected me for quite a while after stopping too.
I see people wasting their lives due to drug use, and I have seen all sides of the drug market, from dealers who I knew well, to the users who are under a delusion that they are not doing any harm to their bodies.
Compare it to painkillers.. fine. If you took painkillers regularly for years, you would be damaging your body.
