Similar to other pills, marijuana can be ingested orally for medical benefit. Sativa capsules tend to have more organic look, it looks like ground up marijuana. These pills are taken based on weight, the more you weigh, the more you take. 1 pill as seen every 2-3 hours for 100 pound female, or 3-4 for a 280 pound male.
Of course this figure can adjust based on strength of cannabis and how packaged. These are great and a traditional way to medicate perfect for discretion. While smoking takes near immediate effect, ingesting casules can take up to an hour to digest depending on your last meal. Take before meal to feel effects fully.
