Cannabis is the best sleep aide "not on the market". It is safe, effective and affordable. It is a very diverse plant and can have different effects based on the genetics of the plant, where it is grown, how it is grown and how is it utilized. Indica and sativa are the two ends of a wide spectrum with hybrids in-between. Indica can put one "in da couch", and aides with sleep, relaxation and pain. Sativa is often more uplifting and energizing, helping with appetite, depression. Utilizing cannabis by inhalation (smoking, vaping, dabbing) is the most rapid method, while sublingual and oral administration take longer to "kick it" and last a bit longer. Edibles and suppositories have the longest duration of effects and often take a few hours to reach peak effects. Start with a small dose and increase as needed.
Everyone is different, so it really depends on what works best for you and may come down to a bit of trial and error. The one thing you’ll want to keep in mind no matter what method you choose is going with Indica strains over Sativa strains. Indica strains relax the mind and body while sativa strains stimulate the body and mind. Beyond that, the method you decided to use will come down to what’s best for you. You can go the conventional route of smoking, but you can also vape, use edibles, tinctures, pills, etc.
