I was gonna write a topic some time ago how useless the most consumables feel (or maybe I wrote it already)
There's currently 2 consumables that are at least semi-useful.
The first one is increasing carrying capacity by 50%, the other one is increasing ram by 2.
Everything else can be just shamelessly sold (with exception of healing items (though even those weakest ones can be getting rid of)). Healing items are just far stronger than these drugs that last like 10 minutes.
Even the ones increasing Stamina generation don't really do much. Perhaps if you're fighting boxing match you could have one but generally not a huge influence.
Definitely they could take some inspiration from games like WoW or even Witcher on how to make these consumables.
Even if it was something as stupid as "Eat/Drink to receive increase of 100 armor. Lasts 10 minutes." it would be better than 99% of the bottles and drugs.
Going little bit wild with them is okay. Add more elements into the game, new gangs that use electric weapons, some that use poison etc, and then introduce these special gear / potions to protect from it.
