I offer you brownies and ask you to tell me what a substantial skill is and you insult me? Why? Reads like you might be bad company.

…

I thought ‘smoking weed’ to be an obvious pars pro toto for ‘consuming marihuana’ so if we want to return to the original topic: smoking weed for a long time gives you substantial knowledge about smoking weed. When to do it, what to mix, how to roll a blunt, operate a bong or vaporiser, just how to roll a spliff in your hand on a windy beach or how to decarboxylate your shot properly. Now are these ubiquitously useful skill? Not really. Are they very useful in terms of getting very high? Absolutely.

I find the original question to be kind of silly. Of course smoking weed can be a hobby. If whisky is a hobby, weed is, too.

Please try some of my brownies and tell me about substantial skill

No option really does

Do something with it

Sometimes, at least.

How rude of me

Man, I’m sorry. You really missed out.
