vic6981	If one eats the resin one will be STONNED!!! (and problies very happy!)
abebibobub2003	people that take drugs are losers, so you could say, that drugs make you turn into a loser. but yeah, in all honestly, drugs will effect you badly all parts of your body, and I mean everything, and you'll be risking death everytime you take them.
tora s	since there are no deaths recorded from schmoking, the most you can catch is a case of the twinkies, then u might become a little overweight................
manabovetime	Cannabis sativa has the terrible effect of causing people to eschew the Republican Party and the Satanic principles it lives by. Seriously, Cannabis, used in moderation at appropriate times in appropriate settings, even long-term, has no known detrimental effects.
recall611	it does'nt effect you at all. I v'e been smoking it for years , and me and my invisible rabbit are as sane as the next...........sorry what was l saying?
andylefty	Long term users can get quite withdrawn and tend to hang around in the same clique of smokers. also your memory and IQ can be damaged/lessened compared to non smokers. they are also more likely to have developed poor dietary habits over the long term with the health risks that that entails.

CyberCommie	If you smoke it all the time you will be a real mess, your brain will turn to Jell-o and you will not have a memory. But if your consumption is moderate and there is no tobacco involved there will be no (or hardly any) deletirous effects over a long time. As to whether it causes mental illness or not, there is a very small minority of 13-16 year olds who smoke it continually who will develop psychotic illness. This stops when not taking Cannabis, it is only temporary. Unfortunatly, a lot of dope smokers take other drugs as well, so in the field studies are rather flawed. To precis, The long term moderate use of Cannabis has no bad effects at all.
justwondering	The habitual users I have know made some of the stupidest mistakes. I would think of them as not the brightest bulbs in the marque. Now that may be all some people are even with out using - but it is a shame to see some one get foggy. No different then the drunk - after a while even if they are sober they just aren't cutting it.
Chocoholic	I think it effects people differently,Im 29 just stopped smoking weed & I smoked every day for about 14 years,I dont have a memory problem or split personality,I stopped coz I got fed up with it.my mate who is about 10 years older couldnt go a day without n her house is a tip,she is overweight & so are her kids,it depends on the person.them people that say it $ucks u up after a time should come & study me!
SuperFishMan	If you mean, "how does that happen?", I believe the answer has to do with oils that become absorbed in fat receptors. I don't fully understand what fat receptors are, but according to the book End Your Addiction Now, which describes nutritional approaches to rehab, it is possible to accelerate detox and cravings for THC by supplementing with omega 3,6,and 9 fatty acids. It is generally agreed to take about six weeks to detox from casual use. If you mean what are the effects, the first answer was really good.
Oh no!	If they mix with tobacco then they are at increased risk of tobacco related illnesses. There is also now a significant amount of evidence that prolonged use of Cannabis changes personality and increases paranoia. Cannabis smokers are twelve times more likely to develop schizophrenia than non smokers
