BTW: The leaves on this plant actually look like cannabis leaves so I
wonder if the two plant are related.

All plants are related, but Cleome and Cannabis aren't particularly
closely related. Cleome is in Capparaceae in Capparales aka Brassicales
in Eurosids II; Cannabis is in Cannabaceae in Rosales in Eurosids I.
Cleome is closer to mallow and maple than to cannabis; cannabis is
closer to rose and elm than to Cleome.
