What are your views on the effects of medical Cannabis?

Your first sentence is a dependent clause which is not completed with an independent clause. "Section of society" is a singular subject and therefore one would use the third person singular indicative form of the verb, ". . . section of society says . . ." Is English your native language?

I've looked at your other thread about reefer, and am now more convinced that English is not your native language. Either that is so, or you are very poorly educated--always, alas, a distinct possibility in the contemporary world, dominated as it is by electronic media.

thanks for correcting me..

You're welcome.

What are your views on the effects of medical Cannabis( negative effect)

Well, that's a rather vague question, although i'm sure that wasn't your intent. Right off hand, i'd say that the only certain harmful effect would come from smoking the reefer. If there is another method of delivery, that problem can be obviated. But we need to know how the drug is intended to be delivered, what the dosages to be used are, whether it is to be self-administered or administered in a clinical setting. So many questions . . .

It's great that you're bringing up this important conversation about the medicinal uses of cannabis! While there's a growing recognition of its therapeutic potential as it related to treatment of a condition, disorder, or disease, it's understandable that these concerns still exist. Like any medication, medical cannabis should be approached with careful consideration and under professional guidance. Research and ongoing studies are crucial to understanding its benefits as it relate to health.
