Hello, I am currently in the MN medical [Edited by Staff] program and I am wondering if there is any such thing as a vape pen/unit that has an inhalation timer. To better explain...my prescription says to take 1-3 puffs up to 10 times a day and that the inhalations should be one second in duration and I would like to not have to pay such close attention to how much I am taking with each puff. So is there a unit where I can set it to cut power to the cartridge after one second? I know most have a max of eight seconds, but that duration cannot be changed. Thanks for reading.
