Can someone tell me if smoking cannabis just as benneficial as cannabis oil?

"beneficial?": There is little scientific evidence that cannabis, whether in the form of oil or smoking marijuana, has "beneficial" effects on most people, any more than alcohol does. For people with wasting syndromes, cancer, aids, hepatitis and other conditions, it can help them improve appetite and gain weight, and perhaps glaucoma and nausea/vomiting from cancer treatment etc. If equally potent, equal result.
