How to minimise risk of throat infections?

I am abroad right now and I only have the means to smoke cannabis which is annoying because I had to switch from smoking to vaping because of a throat infection last year.

Ive been smoking again the last 2 weeks and I've got another throat infection. Wondering if anyone has any tips on how to smoke and minimise the risk of a throat infection? I'm aware vaping and edibles would be the most logical answer but I just don't have the means for that right now while I am traveling around a lot (no kitchen to cook edibles in and unable to get a vape online due to no address). Got 3 weeks left of my holiday and ideally would like to spend the rest of it high once this infection is cleared without getting another one!
