Ajira in the mages guild is much better to sell moon sugar too. Since you can easily get a high disposition with her even if you're low personality/mercantile. Doing her initial quests means you can easily sell her moon sugar for more than 50 gold each even with low stats. She also has a larger pool of money.
Pros and cons of Skooma: Pro: It tastes good, taking enough of them sends you to the Joe Rogen podcast, ZOOM, the government says its bad for you so it must actually be really good for you, lean Potion. Cons: Soyjack Wizards and other Coping Sharlatens will try to use big fancy words and so called "magics" against you, but a true Skooma Chad is simply too godly in both mind and body to be fazed by such needlessly complex concepts.
in morrowind at least, I feel like skooma is kinda pointless, since the other drinks are cheaper and do just about the same thing. one bottle of skooma will buy you like 10-16 of the other drinks (depending on if they are 50gp or 30gp) so it's pretty much always the best move to sell the skooma and either buy something else or make your own fortify potions
