You’ve done your research. You know which strain of marijuana you want to purchase. You’ve found a dispensary in your location. You’ve found the right products to consume cannabis in your preferred method. But how do you know what you’re buying is actually good?

Here are 10 ways to distinguish between good cannabis and bad cannabis.

1. Color

Color is one of the easiest ways to tell if your marijuana is high quality or not. Good cannabis is green, with flecks of orange or purple. Brown cannabis, however, means its bad and could contain mold, pesticides or other funky stuff.

2. Smell

Another easy way to determine good cannabis versus bad is smell. Marijuana should have a fresh smell that you can detect easily. Bad cannabis will smell like hay or grass. Basically, if it doesn’t smell like cannabis, don’t smoke it.

3. Taste

Taste can be a little harder if you’re not a more experienced marijuana user. Good cannabis should taste fresh. If it tastes off or not fresh, then you should avoid it.

4. Crystals

You know those crystals on your marijuana? Those are called trichomes, and they determine how much THC is in marijuana. So if someone tells you they have some potent cannabis and you don’t see any crystals, don’t believe them.

5. Feel

The texture of marijuana is also very important, and also very finicky. Properly cured marijuana should be slightly dried but also still sticky. If your marijuana isn’t sticky, that means it’s probably dried out and will turn to dust easily. But you also don’t want it to be too moist as well. You want it right in that sweet spot: a little dry, and a little sticky.

6. Seeds, Sticks and Stems

Good marijuana will have none of the three S’s mentioned above. It should have very few sticks and stems holding the bud together, and there shouldn’t be any seeds. The thicker the bud, the better.

7. Orange Hairs

When marijuana is well-pollinated and matured, it will grow little orange hairs. That’s the sign of a high quality strain of cannabis. If you see orange hairs, then you know you’re getting the good stuff.

8. Well-Trimmed

This won’t necessarily tell you if marijuana is good or bad. But a well-trimmed bud without extra leaves or stems shows that cannabis was maintained well and whoever grew or sold it takes care of their product.

9. Contaminants

This one’s pretty easy, but if you see something off about your marijuana, don’t smoke it. Make sure to check your cannabis for mold or little bugs before buying. And if you see any thin, white hairs that look like a spider web, that’s probably spider mites. Avoid that as well.

10. Tested Products

Another way to ensure your marijuana is good is to purchase only lab-tested products. This may not always be an option, but if you can find product that’s been certified to contain little to no pesticides and other contaminants, then there’s a pretty good chance that it’s good.
