Last night when I went to bed I placed my pv's on the nightstand just like I always have. Everything was fine. This morning I picked up my vmax with a ST drilled boge carto in a 25mm IBTank. Tried to vape and it felt like it was plugged up. Not to get into the ordeal of all that happened next, when I got to work and got some time, I took the drip tip off. The air tube is not clear anymore. I tried to blow through it and Just very little air passes through it. Is it possible for the air tubes to colapse?
