Do I need specific THC/CBD ratios to treat ADHD and autism with cannabis?

Dear Dr. Dave,

I have a 9-year-old boy with mild ADHD and mild autism. I am interested in medical cannabis. I live in Cyprus, where it is illegal, but I can purchase it. My concern is, do I need to know a proportional ratio of CBD and THC? My son lacks concentration, has social problems and is hyper at times.

Dear Christina,

As you may be aware, the United States government has effectively blocked almost all whole plant cannabis research. This means that we are left with experience, basically trial and error. My experience has generally been a relatively low dose of THC (2.5 or 5mg, 2-3 times a day) is effective. This can be equal amounts of THC and CBD. For autism, sometimes low dose THC (2.5-5mg) with a higher dose of CBD (10-25mg) is most helpful.

All the best,

Dr. Dave
