It may seem ironic to suggest a drug to help with drug abuse but imogaine, a naturally occuring psychoactive from the iboga plant has been found to help with heroine, alcohol and cocaine addiction.

‘Anecdotal reports also suggest that ibogaine may have potential to drive introspection that helps elucidate the psychological issues and behavior patterns that drive addiction or other problems.’

‘Due to its hallucinogenic properties as well as risks for patients with certain health problems, it has been placed in the strictest drug prohibition schedules in the United States and a handful of other countries.’

‘While ibogaine’s prohibition has slowed scientific research into ibogaine’s anti-addictive properties, the use of ibogaine for drug treatment has grown in the form of a large worldwide medical subculture.’

‘Ibogaine is now used by treatment clinics in 12 countries on 6 continents to treat addictions to heroin, alcohol, powder cocaine, crack cocaine, and methamphetamine as well as to facilitate psychological introspection and spiritual exploration’

It kind of annoys me when tax payers are regarded as responsible when it is they who are supporting a society responsible for all kinds of enviromental and humanitarian atrocities – such as the laws against vagrancy.
When I first found out, as a child, that in some places it is illegal to be homeless I couldn’t quite believe it.
Having been a ‘new age traveller’ myself in the UK I know what it feels like to be cursed, moved on and regarded as ‘world-class dregs’ simply for wanting to live in my own vehicle.
