You can give multiple meaning to freedom: 1: i am legally allowed to do X 2: I am legally allowed to do X and you are forbidden to prevent me from doing X and you can even push to this one: 3: I am legally allowed to do X, you are forbidden to prevent me from doing X, and i am able to do X without discomfort/sacrifice (this can be broken into smaller parts too, but i think this is enough) Freedom implies moral responsibility of your choices (this can be debated, but i think the modern debate lean to that conclusion): if you are enslaved and are not responsible, you have no freedom at all. So physical addictions remove your freedom. You can do thought experiments about which addictions remove your freedoms and which do not, but i recon most drugs won't really change your freedom.
