Maybe. I am a firm believer that your rights stop only where my rights start.

I would not be against drug use by other individuals (even if I personally think it is a stupid idea). Unfortunately, drug addicts do their best to make their problems your problems (i.e. they externalise the consequences of their actions).

This is manifested in such things as free health care and constant welfare and unemployment benefits. So, yeah, if you want complete individual freedom, it should be coupled with individual consequences.
