I'm really sensitive to cannabis; low to moderate doses of it leave me unable to speak coherently, mess up my coordination, give me shakes and closed-eye visuals consisting of bright, shifting colours and do something to my sense of balance that makes me feel like I'm on a roller coaster. It's also done other weird things to me on occasion; one time it turned my skin into one big erogenous zone and gave me a pre-orgasm sensation wherever I touched myself, though I was with a group of people at the time, and thus didn't fully explore the possibilities. I find cannabis too intense and incapacitating to use regularly, but it's interesting to take on rare occasions.
That's what I do like of cannabis. 
Only need a few puffs for that sensational effect.

It's the people around you that will make the difference I guess. 
I think it's down to the chemical composition of the material being smoked. I got the pre-orgasm sensation from smoking some fresh, high-quality bud, that probably had a high level of THC compared to other cannabinoids. When smoking or ingesting lower-quality or more aged materials that are proportionally higher in THC degradation byproducts, I tend to get less pleasant physical sensations like dry eyes, electric shock sensations that pulse through my body and uncomfortably descended testicles.
It was Orange Bud that never failed to turn every spot in me into an erogenous zone.Very nice. Other flavours did not have that effect. And there was enough in the effects that I did not really like, like indeed dry eyes, and sideeffects of the tobacco on my windpipe and lungs.
Especially smoking Cannabis when ill at ease brought bad effects.
Like alcohol, for me it works as a mood enhancer. Worked great helping me relax deeper, if only I could start relaxing without the aid of THC.
