Other Aspects To Look Out For Aside from the color of the ash, there are other things you can observe when smoking your cannabis.

One is the texture; good-quality and clean cannabis has a delicate and light texture. If it was harvested leaving leftover fertilizer, fungicides, or pesticides, then the ash will come out as hard and grainy. Generally speaking, you want the ash to be similar to a fine powder. You can test it by taking a few puffs to see if it will produce any ash that you can examine, then take note of the texture at different times of smoking the joint in order to get more accurate results.

You can use your senses to learn more about the quality of your weed, too. Visually, look out for mold at all times. If cannabis has any signs of mold, discard it immediately and don’t even consider cutting it out then smoking it. On top of that, avoid consuming cannabis that is brownish or yellowish in color.


Use your nose, too: cannabis always has a very specific scent which you’ll get to identify better the more you consume cannabis. Always avoid cannabis that smells grassy, or like hay. Conclusion Learning the many ways to identify better quality cannabis is a terrific way to start getting to know the plant better. This helps especially if you eventually want to learn how to grow your own cannabis.
