This should have all the info you need ^
1:1 is fine. And yes, it means you use the same amount of each. So in your case 50mg plant material and 50mg dmt. But really, its silly to make a batch that small...People usually do a gram or more each, not just one or two doses worth. If 50mg is all you have, you can just put a bed of caapi in your smoking device, put the dmt on top, and then just melt it into the caapi using a lighter. Then wait a bit, and smoke.
Oh and don't use caapi vine, use caapi leaf...and/or other herbs/harmalas :]
<Ringworm>hehehe, it's all fun and games till someone loses an "I"
