Answer
Use letters to represent each simple statement in the argument.
p: We criminalize drugs.
q: We damage the future of young people.
Express the premises and conclusion symbolically as:
\[\frac{\begin{align}
& p\vee q \\
& \sim q \\
\end{align}}{\therefore p}\ \ \ \ \ \frac{\begin{align}
& \text{We criminalize drugs or we damage the future of young people}\text{.} \\
& \text{We will not damage the future of young people}\text{.} \\
\end{align}}{\therefore \text{We criminalize drugs}\text{.}}\]
The argument is in the form of Disjunctive Reasoning.
Thus, the argument is valid.
