This is interesting personal testimony. For anyone curious about a more scientific view of this issue I would recommend the book High Price by Dr. Carl Hart.

While it is common for people to believe strongly that drugs are bad and addictive, actual scientific observation of drug users finds in many cases there is little evidence of harm and instead of forming an enduring habit they follow a progression which is more like a hobby. There are plenty of comparisons that might be made, but driving seems an apt comparison. Driving is extremely dangerous, magnifies even small mistakes, and kills or maims very large numbers of people on a regular basis. And yet even with similar evidence of harm and habit formation people do not treat driving with the same fear but instead face driving with irrational positivity and optimism. Scientists using rigorous observations and mathematical analysis do not see drug use and driving as having risk profiles that are completely different.
