Some of you may already know my general opinion/stance on recreational drugs, it can be summed up in two words. Absolutely Haram.

The closest I've ever come to an issue would perhaps be painkillers, just OTC ones which I had to have for several months. All the while wondering about if I was going to end up addicted to the bloody things. Turns out I wasn't, I came off them after about 6-7 months of prolonged usage without a single hitch. It caught me by surprise though, because I'd have thought that considering my mother's propensity for addiction (Alcoholism/Chain Smoking) and how I can see it manifesting in my brother (Online games, facebook shit) I'd have been in the at risk category. But it looks like I was dealt a decent hand of cards for my genetics <.<
So I was able to drop them cold turkey overnight and I didn't have a single physical or mental symptom of withdrawal.

That all being said, not everyone is that lucky. Some people are born with a predisposition to addiction, it's not a matter of being weakwilled anymore than being born without legs makes you lazy. You get dealt a hand of genes and you get some good ones and some bad ones, some people are born with that predisposition and if they are then born into an environment conducive to addiction it's basically an uphill battle from the get-go.

People who are addicted have a medical problem, not a lack of morals or willpower. Yes, willpower does factor into it but at the same time it is not the be all and end all of addiction matters. And that willpower itself is likely determined by your upbringing/genetics too.

So if someone is addicted to anything judging them for it is as flat out retarded as blaming someone for getting cancer.

Now if I get some more time later, I can go and drag up the sciencey shit for all this^
