"Drugs are just a way to avoid dealing with reality."
Well, yeah. Reality sucks. Reality is pain. Reality is suffering. It's people you love dying. It's working yourself to death at a job you don't really care about & still wondering if you'll have enough money at the end of the month to cover the bills. It's wondering if you'll still be able to stand your spouse once the last kid leaves for college. It's your body falling apart as you inevitably get older no matter how much exercise you do or how well you take care of it. It's the hollow emptiness of a Sunday afternoon when nothing in your life has flavor. It's watching the rich & connected get away with pretty much anything while concepts like honor, justice or fairness are all dependent on how much you're willing to pay for them.
You can smoke a joint & realize the power bill will eventually take care of itself. You can do mushrooms & see the world in vibrant technicolor rather than the washed out mess life's mud has kicked into your eyes. You can chew peyote & feel the tug of gravity from the sun. You can drop acid & hear singing from the Holy Hosts with Duane Allman on slide guitar. I personally don't care for pills or opiods but they, at the very least, help people forget how utterly miserable life in these times are.
Life may suck but people don't deserve to have that life destroyed by fear & anger just because they want to forget.
