Frankly, go for the real thing. God/Gaia/Whatever has a pharmacy far superior to inNova-Pharmacorp, or whatever. The real thing also has documented anti-depressive, and neuro-regenerative (in the medulla) properties. (sorry, you will have to Google them thar ideas) A clean sativa strain is also very uplifting, quells nausea, stimulates appetite, and has multitudinous other of benefits. I have heard of some very "dopey" effects from Marinol.
