In the USA and many other places, one is not allowed to do what one likes with one's own mind. (For those who haven't gotten the memo.) Whether that's right or wrong, potential legal consequences alter the in vacuo definition/calculus of "responsible use".
If one decides that legal consequences are no matter, and if one disregards the consequences of any effects on others, then another option is to find or grow one's own. Indeed, in some but not all jurisdictions, magic-mushroom spores (for microscopy purposes only, of course) are perfectly legal to possess and even mail. For non-plants and non-fungi, the analog, I suppose, would be to thoroughly master practical chemistry and synthesize whatever one wants for oneself in a home laboratory.
None of this is legal advice, of course. Don't break the law. And carefully examine and consider past, present, and future life choices.
P.S.: I see many other comments mentioning that weed or other drugs are "legal" in certain states. Don't be duped: many of the substances they refer to are still illegal federally. Federal law is distinct from state law. The federal government's policy (if any) of not enforcing certain laws does not mean it can't or it won't. Again, none of this is legal advice.
