I’m considering starting MJ again after a two/three month break. I’ve got some 5mg and 7.5mg pens stockpiled in the fridge, but obviously don’t want to start on such a high dosage. My concern is that I will be using the pen for about three months, and I know it’s supposed to be discarded after one month, but I obviously don’t want to waste such a lot of money. So my question is (at the risk of being lambasted) has anyone used a pen for that length of time with success and without issues?!
