Yeah, smoking week is basically guaranteed to cause anxiety for everyone if you smoke "too much". I used to hang with lots of stoners and basically everyone had stopped because while it was fun as a teenager, the anxiety slowly crept back into lower and lower dosages until the only time it was doable was if you're alone at home playing video games. Then the social circle fragments and disintegrates until everyone grows up enough to realize that that sucks and we'd like to hang outv again please. Similar cycles can be seen with friends groups based around pretty much any other drug besides coffee and cigarettes i'd assume
