I don't believe benjamina is toxic, however it does contain a possible irritant. The white substance that comes from breaking a branch can cause problems if it gets into a chameleon's eye. Many people use this plant species without problems, but there is a risk. Logically this risk would increase for frequent plant eaters.westcoastchameleons said:I have heard reports of ficus' being a toxic plant towards some chams if they eat the leaves. So you should consider getting a non-toxic plant!
