In Russia, they have developed a drug called Krokodil (or desomorphine), which is backyard created by mixing over-the-counter pain medications with ethanol, petrol, red phosphorous, iodine, hydrochloric acid and paint thinner and warming it up a bit. It can be produced very cheaply, and was used in Russia when heroin was hard to get.
The drug causes scaly patches to erupt on the skin, abcesses and horrible death usually within a year.
If anything could prove to you the drive some people have to escape reality, then this should be proof.
In short, you still seem to believe in the old 'pusher' model of drug abuse where a smooth talking dealer approaches some innocent kids and 'tricks' them into using some drugs and they instantly become addicts. No. That's not how it works at all.
People seek out drugs because they want to use them in most cases.
The demand factors must be dealt with.
