Most cannabis users will encounter moldy weed at some point, the pressing question is of course “is it safe to use?”, and the answer, unfortunately, is no! Especially if you have a weakened immune system or existing respiratory issues – as many medical marijuana users do.
Our advice to anyone with moldy weed is don’t smoke it, don’t vaporize it, definitely don’t cook with it (mold spores are far more dangerous to ingest than inhale). Don’t try to make green dragon or hash oil with it. In fact, the only thing you should be doing with moldy weed is throwing it out! I know, just the thought of throwing out weed breaks my heart but it really is for the best. Some of the nasty effects that you may experience if you have inhaled or ingested moldy weed can include coughing, diarrhoea and vomitting, although the reaction can be much more severe for those with existing health issues. Even for healthy people, mold poses a significant risk when inhaled or ingested and can lead to chronic infections that will grow worse with time.
Can You Die From Inhaling Moldy Weed?
To our knowledge there has been just one recorded death that could be attributed to smoking moldy marijuana. In this particular case the man already had health complications.
What Does Moldy Weed Look Like?
Have a close look at your buds for any black, dark green, blue or yellow spots, any white or light colored ‘fluff’ or any other unusual coloring. Moldy cannabis will also tend to smell more musky and unpleasant. If you’re still unsure about what to look out for then take a look at these photos, all of the buds here have mold on. Some are very obvious, some less so but all could potentially be a hazard to your health.
How Can You Prevent Moldy Weed?
Mold requires at least 15% moisture to survive. So the primary defense against mold is to keep your buds dry. The best way to store cannabis is vacuum packed, in a cool and dry place. Mason jars are ideal. Refrigerated is great, however it is not advised to freeze cannabis as this could cause it to lose potency.
Freshly harvested buds should be allowed an adequate amount of time to dry in a well ventilated area. During the curing process jars should be ‘burped’ (opened) every 12 to 24 hours to prevent risk of mold.
Can Moldy Weed Be ‘Saved’?
Unfortunately not. There is no way to remove just the mold from an affected area without leaving spores behind. If you really can’t bear the thought of throwing out your weed then remove the moldy parts entirely (very carefully) and leave the rest to dry in a well ventilated area with a low humidity. If no new mold has grown then store using the above method and smoke at your own risk.
