Everything I read says THC turns into CBN over time. Which can be a good or bad thing depending on what your looking for. My question is will THC still degrade if it is in a tincture like alcohol or an oil like MCT or vegetable oil? In Canada, specifically Ontario different oils are available for sale on the OCS (Ontario cannabis store) So these products are tested with their percentages printed on the label, but if the oil is a year old is it still the same? I guess the same rules would apply to carts.

Great question, do the government oils and tinctures come with a use-by date?

Probably wouldn't trust it anyways, but, would be interesting to know if they deem a shelf life for these types of products

The bottles say there is 'No expiry date determined'. To my knowledge, THC only degrades into CBN if it's oxidized, which can only happen if conditions are right (i.e., in the presence of an oxidizing agent). I'm not a chemist so I'm not sure what the interaction between the cannabinoids and the carrier oils (in these cases, Grapeseed and MCT) is, but, I'm pretty sure hydrocarbon-based materials (like oils) do not allow for oxidation so, theoretically, assuming they are not subjected to excess heat or light (which I know can affect the cannabinoids as well as the oil negatively, though I'm not exactly sure in what ways), they would keep indefinitely.

Anyways, just my two cents. To be taken with a grain of salt as well as some more googling on the topic... ?

I have no idea eithers but if i had a bottle for a long time say a year or 2 i would just replace it rather than take the risk lol

This makes a lot of sense as to why they would use these types of oils in the tinctures, but, how do alcohol and extracted cannabinoids interact with one another? 

I love CBN anyways, I always use my already vaped weed in edibles and they rock your face off lol

@templegrower

thanks for that response. I believe they do weaken over time even if left in a cool dark storage.  I have a bottle that is over a year old from an LP but not willing to pay $200 for testing just to see.

Quite a few times I’ve made some Heinz 57 herbs into oil and it’s the most horrible shit ever. So I jar it up and leave it for a few months and surprise, it tastes better n fucks me up. I’m no chemist either but believe if it’s sealed up good it should last. 

It is better to keep one’s mouth shut and let everyone think You’re a fool than to open it and prove them all right
