Sativa
There are two major types of Cannabis plant: Sativa and Indica. Each strain has a varying range of effects on both the mind and body. Hybrids are a combination of both, bred for the combined effects.
Used mostly in the day time, Sativa strains typically give you a more uplifting experience. The effect is usually a light, happy, energetic one. With some as stimulating as coffee, Sativas are great for uplifting moods, social occasions, mind stimulation, creativity and physical activity.
Indicas on the other hand, are mostly used for relaxation as the result is a heavy, mind-clouding one. Pain relief and physical sedation are common quests.
