you are allowed to have 2.5 ounces on you for personal use.
Idk about illinois exactly but its probably very similar. When i lived in ohio the fine was like $100-$500 for possession under 100 grams which i couldnt believe. This was before legalization in illinois so i was stoked that having a few oz on you is a felony in one state yet a mere traffic type citation. Oddly enough, the part i lived in had crappy reggie weed and having good proper hydro was rare and super expensive. That changed quickly ; )
Lenka the cops will try to get anything they can. If they can send a pipe to the lab and if it detects weed or whatever the prosecutor will def use that.
I remember hearing that in poland there is a penalty for smoking weed around people. So if ur smoking a joint on a bench and other people are around and a cop catches you there may be additional charges besides just possession.
Weirdly enough the weed laws seemed on paper more lax under prl than afterwards. Not many people were smoking back then though. The more popular drugs bacl then were "polish heroin," relanium which is like valium, and solvents.
Ive been smoking on a girl scout cookies sack from last week. Great energetic/ and europhoric sativa head high and not a coucher. Speaking of which i think its time for another blunt....
