Wow, that must have been some terrible stuff, laced with other chemicals as well.... I honestly can say I Know 200+ people within the last 10 years who smoked/smoke pot and none of them had terrible effects from just marijuana. I however, nearly died after smoking a joint, was sent to hospital where I was in convulsions, vomiting (choking) had to have my stomach pumped, put on IV and even had to have CPR done until arriving at hospital by ambulance.
When they found out I had just smoked pot, they knew that medically it couldn't do what it did to me.... they did a toxicology screen and found high levels of cocaine and many other added chemicals in my system which reacted against each other, along with a rare allergic reaction, which caused such a traumatic experience.
If you aren't smart enough to get it from a well known source personally (which most regular smokers do......) then no, you shouldn't smoke it lol... it's called using common sense when using anything, just like if I have a drink or two I wouldn't get homemade from some weirdo down the road haha... lord know, he could have pissed in it!
Even with my experience I am still not against marijuana. I do not smoke it myself, haven't since high school but I know MANY who do, some in very high positions at their job, some you would NEVER expect them to do it at all, and they are successful and very good parents!
It's not fair or intelligent to class everyone as the same who smokes marijuana and shows some clearly haven't a clue (which isn't a bad thing, it's best not to smoke it or know loads about it) but I think if lack of knowledge is present on a subject, maybe one shouldn't comment and be so judgemental.... kwim?
