Schweppes has 67.9 mg/L of quinine.

I lived in SE Asia for over 7 years with close to 2 years of living in remote areas with dengue and malaria. I drank my Schweppes tonic water because I am sober and enjoy the bitterness, and it gave me some peace of mind that I was keeping quinine in my system at any level.

Having cobra anti-venom was a lot more important where the nearest trauma center could be 12 hours away by vehicle due to winding, mountainous, and difficult roads before hitting a real paved road.
