No I don't have friends who are class a addicts but I've known a few.
Sorry, your missing the point ... you do .... but you don't know it .... addicts take class A drugs not to get high ... just to be normal ... to appear normal .. to act normal .... what ever normal is in their peer group ..
And they buy their drug of choice from dealers who couldn't give a monkey's whether they live or die,it needn't be like that,along with kids as young as 10 running their drugs for them,it needn't be like that.
Then there's the thieving,fighting,murdering and drugs wars over markets,attached to the trade in drugs,it needn't be like that.
And the NHS being overwhelmed as it is,having to treat addicts using dirty needles,and heroin mixed with all kinds of crap to make it go further for more profit for dealers,it needn't be like that.
The war on drugs is lost anyone who thinks otherwise is deluded,the dealers have won,taking it out of their hands and regulating it can only be a step forward for users.
In a regulated and legalised system if people want to use they at least can buy a standardised and clean product,with clean free syringes and needles and could seek help within such a system for their addiction if they want it.
As things stand it's a mess with the gangest drug dealers the only winners and everyone else the losers.
