First, Purple Haze is a 100% sativa haze strain.
Thai weed is 100% sativa
Strawberry Cough is 80% sativa
Afghani is 70% sativa I believe
Any haze strains

Finding a 100% sativa strain is hard to find, as well are extremely pricey because of their potency.

Indicas are used mostly by medical users as it eases the pain much better than sativa.
