Plenty of good used cars sitting around but some people just can't live with a car a few years old. Meanwhile I pride myself on driving things that would likely be in the junkyard if I wasnt

This is why we can't have nice things

Enchanting will be the hardest and most time consuming but pretty important.. Smithing without mods will also take a decent amount of time and be fairly annoying to do.. Alchemy will be the easiest as long as you have the ingredients and know which potions to make. Alchemy is also the most important of the three, because if your really good at alchemy you can make iron weapons/armor that can kill several alduins in one hit and make a single piece of armor that will exceed the armor rating cap. Plus the added benefit of creating potions that will take you from 15 to 100 speech in a single transaction (it's okay that npcs won't have that kind of gold) plus alchemy is the fastest way to make money in the game at 100.. I'd almost just worry about alchemy and then enchantment personally.

How about massive free psychedelic doses?

Carry on or on you don't put that in check bag imo. Not saying to do this at all. Also depending on how much you know about the security, if it's just metal detectors you might be able to walk it thru on you in a smell proof container in a sock or something. How ever I wouldn't even attempt something like that with the new 360° scanner style detectors. Those go off randomly even when your pockets are empty. Ive also never attempted such going thru customs/international borders which would likely be much riskier both in getting caught and the repercussions.. like others are saying I'd really recommend scoring some that's already in your country. Let someone else be the mule.. also I never commented on this post if anyone asks js
