Marijuana Effects: Sativa. Sativa strains are more of a stimulant, and are effective in appetite stimulation, relieving depression, migraines, chronic pain and nausea. Common strains include: Haze, Trainwreck, K2, Kali Mist White Russian and Kiwi Green.

Each grower is basically able to tailor their desires to their individual plant with the numerous varieties of marijuana plants available right now.
