Hello and thank you for using JustAnswer Health.

Synthetic cannibinoid has not been studied in controlled research trials, so it is not known for sure how long it takes for them to be metabolized, but likely it is similar to the length of metabolism for natural cannibinoids, since the chemicals are similar in many ways. It is possible that they could stay in your system a bit longer, since they may be placed in stronger amounts in the smoking products.
Therefore, it depends on how much and often you were using it. If you used a small amount one time, you might expect it to be out of your system in 3 to 5 days.
If you used a large amount daily, it may be detectable from a month to 3 months.
Most drug screens do not check for synthetic cannibinoids at this time.
