Due to marijuana's history as an illegal substance, many people suffering from ailments that could potentially be treated by medical cannabis are scared away, which is why the Releaf app is foraying to ease the process. The medical app lets patients track their own usage and draws from an anonymous pool of user data.
Since cannabis is a natural substance, its effects are less precisely predictable than those of pharmaceutical drugs. While this doesn't preclude cannabis from being a helpful medicinal product, it does mean that the same strain can affect two people differently. The Releaf app lets users track their medicinal cannabis sessions, recording each change in their experience on a puff by puff basis to get precise data. The app also enters this user information into its anonymous database, creating a crowdsourced research tool for strains and usage info.
