Cross-behavioural addiction, or dual-behavioural addiction, is pretty much the same. Let's say you have an addiction to alcohol, there is a big chance that you might smoke cigarettes or gamble too. The reality is very few people have one addiction and one addiction only, they have cross-behavioural addiction or dual-behavioural addiction. There are particular propensities – biological, genetic propensities, and psychological, social propensities. But, generally, people have multiple ways of making themselves feel good – which we call cross-addiction or dual-addiction. Sometimes, if you ask someone to give up one addiction – in other words, give up the way they know how to make themself feel good – they pick up a cross-addiction, and that way they're substituting one way of feeling good for another way of feeling good.
