May I add with all due respect that the carts should be kept up right at all times when possible, i know this isn’t possible to control during transit.

I know this as I have had lots of carts that have smoked smoothly and only got a little clogged towards the end which is natural then I have had carts where ive opened it at night to have a few tokes and woke to it really clogged. I know you most probably keep them up right at all times anyway I just thought i would say as it definitely can affect it being clogged
more. I researched this online and a few people on different forums spoke of this. This is only rare that is happens by the way and also vaping on a low wattage between 7-8 watts is ideal. Try not to let residue, condensation, spit into the mouth piece too as I think someone mentioned the water mixes with the left over vapour in the mouth piece and then.....tadaa, clogged cart.

I just thought I would add this to help anyway stay blessed people 💚🙏
