Well, good to see more. Although, and I thought this earlier too...he should really just quit the drug-dealing. On the level of a direct dealer the profits are just way, WAY too low to merit the risks of military tribunal, and while Konoha might turn a blind-eye to mary-jane trafficking like they do the Ring... it's a behavior they (or more accurately some official in any faction with authority over Takuma) could change at any time to suit their agenda.
At this point, he's got the better job that pays more money, and frankly a lot less time on his plate between the new training, responsibilities, and self-determined training that Uchiha resources will increase the possibilities for. Oh, and the fact that Takuma is still adjusting to the Weapons Division in the Ring.
Trying to maintain being a drug dealer on top of all that, with great risk, for crappy amounts of money, just seems a bit too much like making the character clutch an idiot ball for the purposes of later drama.
