There are ways to smoke weed without coughing. This is typically the result of not learning how to do it correctly. The easiest way to fix that? Learn how to inhale, vape, or smoke it correctly. However, if you have just started smoking, there are ways to prevent coughing right off the bat. One of the best ways to do this is just to know your lung capacity. Taking a bigger breathe than you can handle will likely cause you to cough.
So, instead of taking a large breathe, work your way up to the larger breathes. Another way to prevent coughing is to cool the smoke down some with a diffuser added to your vaping or smoking routine. Heat will make you cough; that’s why some people cough when they have really hot peppers.
