My friend used to be such a light weight he couldn't even smoke a whole bowl. He was sooo fucked up too. We have really good chronic though, and he never really smoked. But him and my other friend started at the same time, one of my friends needs four bowls, one needs a half. It's all based on body weight and genetics I think.
You're blessed to say the least, but if you start smoking daily, that will end within a month.
