This 2015 Conversation article claims that most users of illegal drugs are not addicted. by Paul Hayes, former chief executive of the National Treatment Agency for Substance Misuse, claims that most users of illegal drugs do not become addicted:
Drug use is common, drug addiction is rare. About one adult in three will use an illegal drug in their lifetime and just under 3m people will do so this year in England and Wales alone. Most will suffer no long-term harm.
There are immediate risks from overdose and intoxication, and longer-term health risks associated with heavy or prolonged use; damage to lungs from smoking cannabis or the bladder from ketamine for example. However most people will either pass unscathed through a short period of experimentation or learn to accommodate their drug use into their lifestyle, adjusting patterns of use to their social and domestic circumstances, as they do with alcohol.
Is it true that most drug users aredo not become addicted?
