My suggestion is a basic idea for a new, hands-on drug making crime. But it would then lead to further additional ideas for other stuff in the game.
First, to go along with the "Illegal Production" heading in the crime statistics section. Unless Ive completely missed something, I don't think this has been enabled for anyon3 yet. So, perhaps there are existing drugs we could "make" (or grow).. xanax, cannabis, ecstacy.. (meth?) This obvious would have a skill rating like racing or hunting has, but one that improves your successes in a particular drug creation. The better your skill, the better quality your drugs are. Perhaps even a worse/better overdose ratio as the skill changes.
But then this leads into other avenues of the game.. real estate like trailer and detached house finally has some use (and value) in the game. A grow op or a meth lab can be an "upgrade" for specific residences (like airstrip is only allowable in a pi). Maybe you have to live in that residence to utilize it.. and now a pi isnt the top place to live anymore.. do I fly and make money trading, or am I a cook making meth? A shack's coat is still sh!t, but now the value it adds to the game coukd be HUGE.
Additionally, items that currently have no use, or new items to be created, can be put to better use than just tradeables. Spoon, fertilizer, syringe.. bunsen burner, beaker, pressure cooker.. new flower (poppy) for opium and heroin drug production..
Several different options that stem from this.
