Having been away and done - hooray! - a lot of work for this essay today, I think some people who perhaps have fewer dopamine receptors than others, might be more liable to like sugar rather too much, although sugar doesn't release as much dopamine/ have as much effect as cocaine etc, which seems to be the drug discussed most.
I'm surprised how interesting I find biological psychology. I'm conceding from reading about all these rats on Class A drugs that sugar could possibly be addictive, but maybe in a different way.
alright, now I'm rambling.
