This rule as we are aware of is for anyone and everyone. It seems that bros. Fardeen and Zayed are exceptions here.
At Ambika Hinduja and Raman Maker Wedding we saw Bros. Fardeen and Zayed Khan smoking their respective buds in public. We aren't complaining much as there were many people who were smoking it out there.
The bros. posed for our camera quite comfortably and looked quite cool on this text.
Anyways we just thought of letting our viewers know about the same.
