It's cumbersome to make on a small scale I assume.... may be viable if large quantity of anethole is at hand but the product is not worth the effort besides posing a threat to the consumers. I got self poisoned while discovering how tho make amphetamine via nitropropene but starting from 4-anisaldehyde instead of the unsubstituted (not sure if it just work's better or that was my misfortune)
P.S. it can be exploited to quit smoking nicotine effortlessly if sick for 2-3 days after taking it (not advised due to missing pharmacology just personal experience) but smoking came back into habit 4 months later anyway.
