Durban Poison.
Imported from South Africa, produced in Holland. Exclusively inbred, never hybridized, 100% Sativa. Large long budleaves, buds are also large and long with lots of resin. A sweet licorice or anise flavour. ā??Upā? high similar to Thai. High yields. Well suited for outcrossing with late bloomers to produce earlier flowering. Also does very well under artificial light. A very popular variety.
THC = 8.6% This is the description from http://www.dutch-passion.nl/engels/info.html

This should be a good strain for you... smoked through a vapouriser it shouldnt affect your fitness. 8.6% is a reasonable THC percentage, so the high should be quite powerful. It should also be productive and functional as the plant is 100% Sativa.
