I am in the US, I'll look into those but I'm a college student so idk the logistics on that lol.An on-demand vape seems like it might suit your use case very well. With the ones I use, I generally do a 0.1g load in less than 5 minutes, but I can also take a puff or two on it every couple of hours or so and vape the same 0.1g bowl from morning till night if I wanted to. This also has the added bonus of not smelling nearly as much as burning your weed and they generally hit like a truck. These types of vapes are a little tougher to acquire particularly if you're not in the US, but not terribly so and the effort is well worth it IMO given the performance of the devices along with the other usual vaping-related benefits.
If you're interested, these are on-demand convection devices:

Lil' Bud & Timber Elite by Vapwood
Imp/Impcognito by Mistvape
Firewood 6 by Firewood Vapes
Ghost MV1 by Ghost Vapes
Stempod/Stempod Si by Modpodlabs
TinyMight (New, based in Finland)
Dreamwood Glow - Dreamwood Vapes Based in Germany I think
There are a couple of other butane-powered devices like VapCaps, Sticky Bricks and the Lotus that also may be suitable, but these are the ones that come to mind.
I really do wish vape carts didn't have the whole death risk associated with them because they're so convenient for school.
Can easily carry it and smoke it anywhere without the smell or the bulkiness.
I'm in NJ and qualify for medical but I heard it's only worth getting for the license itself as the weed isn't as good as black market stuff, especially for the markup.
