Suppose someone bought a car, and found out that the car vents were spewing somewhat toxic that has a slight chance to kill them. If they needed to go to work in it to put food on the table, can you see how someone might say they had no choice but to use it?
Now take that logic and apply it to a vape cartridge. Say someone bought that cartridge which carries so many doses, along with paying the cost of the physical vape machine and the cost of electrically charging the machine, and spent the necessary time and emotional cost to wait for the machine to do so. Then they find it out it may be toxic. Is it really a realistic choice to take the financial and emotional burden of throwing away the cartridge, if it provides a needed soothing relief to their mind?
It's funny to read this here because that's exactly what happened to me. I was driving a diesel car with a damaged firewall, which meant carcinogenic diesel exhaust fumes came through the floor and vents. I had absolutely no budget for a car, as I was paying for expensive medical insurance and bills. I had no choice but to drive it with the windows down. My clothes would smell of diesel after driving. I took it multiple times to the dealership until they found the problem, and they said it would be more costly to repair it than to buy a new car.
Fortunately, I eventually bought a new car. But I still might get lung cancer in the future.
