Probably not related: The sequence is important. Smoking marijuana can irritate the lungs in sensitive individuals and an in say asthmatic this could persist. This could cause chest tightness. Smoking a small amount of marijuana seven days ago should not cause chest tightness. If your chest tightness started 7 days later they are probably not related.

Get checked out: The problem with smoking weed is that the weed sometimes comes mixed with other substances. Since your symptoms came after smoking weed, (if you did not grow it yourself), play safe by seing your medical provider. Good luck.
