Personally speaking and, as you know, not even being an active user of anything other than prescription meds. at this time, definitely not.
If they came up with a vaccination that would vaccinate against the psychological or emotional reasons for using drugs in the first place: then maybe. Or get their shit together to help improve the lives of people. Now there's an idea. Damn sure that would solve drug abuse problems to a large extent. If you just tally up the TRILLIONS of USD in the hands of only a few: they could afford to give every member of the world's population $1M USD and still have a substantial amount of spare change. Exclude children i.e. only include adults of working age in the exercise and the amount required would be less. Of course there'd be many that would simply smoke or snort or IV the lot away but that's where the Darwin Awards would come into play. I believe in the vast majority of cases they would use that money to improve their living conditions, maybe open businesses, and put it to good use, and feel like they have purpose and a place in society. Matter of fact: in the UK they did a social experiment some years ago with people that were, and had been, on benefits for years and years. In exchange for signing off benefits for a year: they were given the equivalent amount of their annual benefits in one lump sum. Long story short: in almost ALL cases their lives changed, they changed their own lives, for the better. All of a sudden they had pride and purpose and made and effort to improve their lives. They just needed a bit of a "leg up". It was followed by much controversy needless to say. But that's what I took from the series anyway.
Sorry. I suppose totally off topic (seems to be the flavor of the day for me today I'm afraid).
So in short: my answer is still "no" UNLESS I HONESTLY believed that my use of an illicit drug was the CAUSE of all of my problems as opposed to the RESULT of all of my problems.
