I disagree with that "life is suffering, so lets do whatever we want".

Also I have no pain (luckily) in my life. I've never had other than when family members died. And I enjoy every day without doing drugs, alcohol or something like that.

In my opinion (and I am aware this is harsh) most of the problems people claim they have are pure nonsense and incredibly trivial. They want to blow them out of proportion so they can add some meaning to their life. It's like trying to deal with boredom in the most destructive way imaginable.

In my mind, the only non-trivial problems are generally health issues (death of a loved one etc.)

What kind of pain do you have that you need mind-altering substances?

We are at the height of our civilizations, we have billions of things to do and billions of hobbies to choose from and research, and explore and.. I don't know what else. We live better than ever, and better than kings used to live.

I can't understand how someone that is healthy, has money to live life somewhat comfortably needs to do these drugs to survive.
