I don’t have the article text — only the headline you pasted. To rewrite the piece accurately (without adding or changing facts), please paste the full article or the sections you want rewritten.

If you only want a tighter, more engaging headline, here are two options that keep the meaning:
– San Antonio hemp retailer sues after city exempts vape shops near schools
– Hemp shop files lawsuit over San Antonio’s change to school-area vape ban

Tell me which you prefer, or paste the article and I’ll rewrite it.
