Below you will find a great article about five cannabis edibles that can aid insomnia! Any of these products would be a delightful alternative to smoking, and they are perfect for a patients with asthma.
Personally, I love drinking Kikoko's Tranquili-tea. This is an easy addition if you already enjoy a cup of tea before going to sleep. Tranquili-tea is also made with chamomile and lavender, which can diguise any cannabis taste. I like to have a cup of tea with a splash of honey about 30-60 minutes before bedtime.
I also enjoy Kiva Blueberry Terra Bites! I have a high tolerance of THC, so I can have a one or two of blueberries if I want to relax, but I am not quite ready for bed. However I would recommend the Kiva Blueberry Terra Bites if microdosing is important to you, and if you wish to have something small and sweet before bed!
I hope this information helps! :-)
