hero - yes smoking dope isn't a problem at all when it comes to donating blood, so go forth and do it!! They don't test for it and it doesn't affect the blood in any adverse way that would affect somebody receiving it. They DO care if you inject or snort any drugs, but smoking joints is fine.

melodious - LOL I definitely do not have any physically activity planned - unless the whole arm-to-mouth action (both smoking and munchie-attack) counts!!

I have donated a few times before so I know the score, and as I said am a regular smoker, but the two have never coincided til now - dunno how I managed that!
