How long are you going to be in Nairobi? I would use a MOM that ships internationally and have it sent to a PO box or to someone you can trust with your life, or just visit a doctor and get a prescription - and when you’re getting the script, ask the doctor which pharmacy you can pick it up at. And treat the prescription as you would treat your passport. Don’t share your Cannabis with anyone.
If you’ve got a legal prescription from anywhere in the world that explains your conditions, take it with you so you can show a doctor in Kenya. The grad students I used to work with (when I worked) would get a medical prescription in Canada, and when going back home for a holiday, take their paper documentation with them, show a doctor and then legal.
But otherwise don’t do it. Yeah, locked up abroad or world’s toughest prisons.

Harare, Zimbabwe is where I used to get LSD from.
