Second guessing myself again,

Cigarette advertising has been banned from television, it does, however, appear in printed material.

Has to be a comma splice sentence to me am I right?

Yes ... and which of the 3 commas is the splice?

I would say--- it does

Before "it does" ... yes.

Yes, you are correct. The sentence "Cigarette advertising has been banned from television, it does, however, appear in printed material" is a comma splice. A comma splice occurs when two independent clauses (complete sentences) are joined together with only a comma, which is grammatically incorrect.

To correct this comma splice, there are several options:

1. Separate the clauses into two separate sentences:
- "Cigarette advertising has been banned from television. It does, however, appear in printed material."

2. Use a coordinating conjunction (such as "but" or "yet") to join the two clauses:
- "Cigarette advertising has been banned from television, but it does appear in printed material."
- "Cigarette advertising has been banned from television, yet it does appear in printed material."

3. Use a semicolon to separate the two clauses:
- "Cigarette advertising has been banned from television; it does, however, appear in printed material."

By using one of these options, you can correct the comma splice and make the sentence grammatically accurate.
