Is my level of drug use normal?

I've only been taking drugs for 7 months, and in that time I've done acid, weed, 25c, 25i, MDMA, ketamine, salvia, and a couple of types of pills. I take some of these drugs on a fairly regular basis- I smoke weed a few times a week, but I would do it every day if I could afford it, and on average I take other drugs once a week, but more recently it has been 2 or 3 times. I never thought I did too many drugs until I realised that I've spent the last 10 days straight on various drugs, and I've only stopped this binge because I've run out of both money and drugs. At my school very few people other than my friends really do many drugs, and all the people I'm well acquainted with at other schools who do drugs have a drug problem, so I don't really have a standard of normal drug use to compare myself to. Is this level of drug use normal?
