Which strand of marijuana is best for the giggles?

[Nochowderforyou]

other way around, sativa is a head high, indica is a body high

Yes.

Indicas tend to give people couchlock feeling. The feeling of being tired, really relaxed and mellow.

Sativas though tend to give people energy, more talkative and exploring.

But I mean, 96% of the strains out there these days are a cross between the two. Pure indicas you don't find often, mostly found in Kush, and pure sativas are even rarer.
