In some what ways: no that is false.
When weed is inhaled, you are inhaling Tar. Tar is a no brainer; bad for you.
Roar (a glass blowing company for tabacoo [bongs]) actually makes a carbon filter, where it filters the tar before the smoke gets in your lungs.
Now the government can't control who uses the a carbon filter, thus another reason why it is illegal. It is becuase you have to buy carbon as well.
Cigarettes are bad too. The chemicals are toxic. And what you think is "tastey" smoke is actually the worst for you. Nicotine is addictive. It can casue cancer, brain damage and other symptoms. Second hand smoking is actually worse than smoking, and its death rate is higher than just smoking.
Again, my 2 cents.
