proofreading thx!!

causes 之前應有一 subject:

Smoking causes a lot of fires.

were .... cigarettes is .... 有錯; cannot 和 smoke 之間不可有 to:

We would all be saved if there was no cigarette, which is addictive.

shop 字似系是錯字, 按上文下理, 應是 stop 較合理:

You cannot smoke just a few times and stop.

have 「been」 started 是被動式的表達, 你「被」開始是不通的; give up 是指戒除:

Once you have started, it is difficult to give up the habit.

We WOULD all be saved if there WAS no cigarette ... (假設性)..., which is addictive (which is 指 cigarette, cigarette 可令人上癒, 不屬假設性範圍, 可不必跟上面用 was/were)
