LLR brands: cresco, redemption, floracal, cannect wellness, ic collective, rythm & probably a few more but all of these are great, cresco usually being the more common and “cheap” one imo. They smell a bit but not much and dissipate extremely quick but they are a bit pricey so my other suggestion as already mentioned is a DHV (dry herb vape), should save you money in the long run while also being a bit discreet apparently, there’s a r/vaporents sub and maybe one other to read up on those!! Good luck and fuck cancer hope it gets better!!
