Hello,

At this stage it is impossible to tell what strain you may have. You may have more luck once it starts to bud.

My guess is that your best bet to finding out is to question whoever your friend got the herb from in the first place. You may also be able to narrow it down once you have a chance to smoke the final product, using potency, aroma, taste, etc., to guide you in deciding.

Hope this helps.

Peace
