Congratulations on finding something that works for you. A lot of craziness going on right now the majority of the individuals who have gotten sick were using either Black Market or apparently their "friends" homemade THC karts in my experience the term "friend" in this context often is also known as dealer or somebody trying to make a quick buck without any actual retail establishment or long-term evidence of online sales. Of course there are some people that have claimed that they only use nicotine I don't know that they've actually verified that however be suspect of any black market dealings and you should be fine as long as you go to a retail establishment to purchase nicotine
vaping supplies. If you have any questions about any online retailer and whether or not people have had good experiences with them do not hesitate to ask people here. In the meantime I would definitely stock up on whatever you're using that is working. And you may want to also try out a few different kinds of items while you still can
congratulations
