Which types(class) of drugs is most important?

hi!!!!!!!!!! guys i need to ask a question about drugs......... i need it now as soon as possible.
which one is most dangerous the medicinal drugs or recreational drugs... and why it is dangerous tell me in detail

Everything in moderation: if you are considering a heroin habit make sure you have the money to fund it :) lol stay away from this one.. i would say this one has the most devastating effect on people.

Don't get fooled into thinking illegal drugs are worse than legal ones (only difference is legal ones are taxed ... governments like this). Cigarettes are probably the worst of the legal ones.. no real buzz.. cost lots of money.. highly addictive etc

Marijuana is popular ... but cant be grown at home and makes you realise consumer products are a waste of time.. so governments and big businesses don't like this.

Cocaine: lifts you up if you feel a little tired while on the booze.. its ok if its pure but can be mixed with bad products ..

The fact is there are 1000's of different drugs and they all do different things and are fun and dangerous to different people... Nuts can kill some people ha ha.. Often the drugs in themselves are not addictive but people personalities often are addictive...Hence anything is dangerous to someone with such tendencies
