Hard to say. I'm no expert. Lot is happening/changing with cannabis research and development. Products made from strains high in CBD and low in THC don't typically get people high, so in that case it's not like someone would be abusing it just to get high. The effects are purely medicinal. I think the cannabis plant is potentially a godsend for many many things, and compared to dangerous synthetic meds, it starts looking very good.

Another thing to consider is quality. Gotta investigate the source in order to avoid pesticides, mold, other contaminants, and to avoid unpredictable levels of potency.
