Summary
Cannabinoids such as cannabidiol can inhibit CYP3A4 in vitro, which could theoretically increase lovastatin levels. Clinical data are lacking and the effect is likely small, so this is not a contraindication.
What this interaction means in plain words
Lovastatin and Marijuana have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Theoretical CYP3A4 inhibition by cannabinoids, mainly cannabidiol.
What to do
No change is routinely needed; ask about heavy cannabis or cannabidiol use and watch for muscle symptoms.
