Well only if you become like terminally drunk. If you take, say, only a single drink, the worst you'll be feeling is a bit tipsy and relaxed, that's all.
Otherwise, there's nothing wrong with drinking as long as you know what exactly will happen, and you understand the consequences of it. The uncontrollable alcoholism occurs only to a marginal group, the vast majority of people can control how many sips they can take.
But rum as a first alcoholic beverage? That stuff's strong. I don't even like the conventional alcohol at all, I'd prefer the hard soda variations of it, like the coolers and hard root beer, the alcohol gives the beverage a more complex flavor.
If you don't want to drink anything however, that's great too! Your choice

but alcohol isn't as life-destroying as some of the anti-alcohol ads make it.
