Answer #1

4. E) NMDA

5. D) both b and c, but not a

Crack is taken in the soluble form. The base form, also referred to as “freebase” is not taken orally as it cannot be made soluble, but it is generally taken through smoke or injection.

9. C) stimuli that are conditioned to the drugs effects

10. E) all of the above.

In this model distress, biological or genetic conditions are considered. This model has been criticised in saying that when people are labelled as addicts, it means that they are kept from developing any self control and this is turn would stigmatise them .
