Substances are also an escape, you just don’t want to feel (or escape) whatever the negative feeling is (guilt, anger, depression, stress, hopelessness, so on).
Which goes back to the original post, in that, you really can’t choose your addictions, only your circumstances (will smith might be a great example, don’t be in a public open marriage, you’re fixing to start picking up addictions that you’ll have no autonomy over).
