It's a meme...of course drugs are never a must, but friendship doesn't live by rules of right or wrong,, act in a certain way or other, and that's what the meme in my perspective talks about.
Either we accept each other as we are, imperfect humans, the duality in each one of us, the good and bad, different belief systems, respect for each other differences, or else friendship cannot flourish. All that is conditional is not authentic. My humble opinion. 🙃
