I've probably spent close to £10,000 in the 13 years I've been taking drugs, maybe a couple grand less. Including the general spending on going out drinking, clubbing, partying, smoking etc I've probably spent about 75% of my money I've ever earned. Have very little to show for my earnings which if I could change I definitely would, seeing friends and siblings a good few years younger than me with mortgages and cars etc. Have had a lot of good times over the years though.
