Doherty locked up for drug use and death of friend. Whats the point?

Pete Doherty has been locked up after footage taken by a friend who died of taking drugs was found of him also using crack. Does it makes sense to lock up an addict? As far as I can tell he hurts no one but himself and prison does not seem to cure him. He surely can't be held responsible for the death of his friend, an adult, who presumable was free to decide for herself whether or not to take the drug that killed her...

If the reason for locking someone up was to try to break their habit then that will clearly fail as anyone who watched the recent documentary series following female prisoners in Scotland will know. They seemed to have almost free access to heroin on the inside as they do on the outside. In the mean time the nations tax payers pay to fill our prisons at considerable cost and rapists and murders get released early so that we can accommodate then. Shameful

Apparently all you need to get high now is your mobile phone??

A new Application has been released for smart phones claiming that it is the new drug for the rave scene.

A British hypnotherapist has claimed to have created an App that causes you to experience a high due to Hypnosis.

“Get "High" without drugs - hypnosis session App helps former drug users,” the marketing blurb for Hypno High™ declared, “No more drugs needed - just the memory of a "high" is enough to revive it.”

I am Sceptical about this one what do you guys think? love to hear your comments
