Sativa,Indica and Hybrid

Well, Sativa's are known to give a more engergetic high, and make you want to do something. This is more of a body high; it might make your entire body feel weird.

Indica's are known to make you tired and very relaxed. This high effects the mind more than the body, making your mind trip more.

Hybrids are basically just mixes of strains between sativas and indicas. If you breed an indica plant, and a sativa plant, you end up with a hybrid. I'm pretty sure this will effect your mind, and your body.

Hope this helped, this is just based on my limited knowledge so if anyone wants to correct me, go ahead

 

The above guy ALMOST had it right.

Indica = A strong indica will give you "couch lock" or put you to sleep. It will make your body buzz. It is good for pain and insomnia. I find Indicas give me the munchies more than Sativas.

Sativa = A strong Sativa will make you feel refreshed and energetic. It is more of a head high. IE: "headies" [although that word is used differently by some people too]. This is a good weed to smoke earlier in the day or if you are going out.

Hybrid = Anywhere in between the above.

 

This. All this is right and to elaborate more on hybrids its a mix of indica and sativa and some are more indica dominant and some are more sativa dominant. Each will give you a different feeling high.
