st: duplicate cases in data cleaning

Hi,
Could anyone point me to how to resolve the following situation
during the stage of data cleaning?
The structure of the data is like this. If an individual has taken any
type of hypertension medicine, then drug is coded as 1.
ID Drug
101 1
101 0
200 1
200 1
Now I need to combine cases by adding up the "drug" variable such that
it looks like:
ID Drug
101 1
200 2
Thank you very much
Jeff
