i see the following difference here:<p>craving - how long you can resist consuming the substance giving for example $1K&#x2F;per minute reward for every minute you resist :) It seems that they are saying that cocaine and sweets are the same.<p>behavioral and psychological toxicity - the &quot;bad&quot; consequences, internal and external, associated with the habit of consumption of the substance. We do know that these consequences are different between cocaine and sweets.
