Smoking it reduces the concentration by about 40% and you are left with similar effects of smoking a cigarette; you’re getting all the carcinogens ( I think thaya what its called) vaping or using a pen is not 100% safe but it is better for you. Or even edibles. They take a while to kick in but last longer.
